“…To examine the dynamics of adsorption process in terms of the order of rate constant, different adsorption kinetics such as First-order-kinetic, Pseudo-second-order-kinetic, Intraparticle diffusion and Elovich were studied. Based on Table S4 , q e and q t are the adsorbed AMP at equilibrium and time t, K 1 , K 2 , K diff , C, β and α are the constants of models, respectively [ 39 ]. According to Table S4 , R 2 value for Pseudo-second-order-kinetic model (0.9932) was higher than that for other models, which confirms adsorption kinetic followed by Pseudo-second-order.…”

The aim of this study is a present of a simple solvothermal synthesis approach to preparation of Cu-based magnetic metal organic framework (MMOF) and subsequently its application as sorbent for ultrasound assisted magnetic solid phase extraction (UAMSPE) of ampicillin (AMP) from cow milk samples prior to high performance liquid chromatography-Ultraviolet (HPLC-UV) determination. Characteristics of prepared MMOF were fully investigated by different techniques which showed the exclusive properties of proposed sorbent in terms of proper functionality, desirable magnetic property and also high specific surface area. Different influential factors on extraction recovery including sorbent dosage, ultrasonic time, washing solvent volume and eluent solvent volume were assessed using central composite design (CCD) based response surface methodology (RSM) as an operative and powerful optimization tool. This is the first report for determination of AMP using MMOF. The proposed method addressed some drawbacks of other methods and sorbents for determination of AMP. The presented method decreases the extraction time (4 min) and also enhances adsorption capacity (250 mg/g). Moreover, the magnetic property of presented sorbent (15 emu/g) accelerates the extraction process which does not need filtration, centrifuge and precipitation procedures. Under the optimized conditions, the proposed method is applicable for linear range of 1.0–5000.0 μg/L with detection limit of 0.29 μg/L, satisfactory recoveries (≥95.0%) and acceptable repeatability (RSD less than 4.0%). The present study indicates highly promising perspectives of MMOF for highly effective analysis of AMP in complicated matrices.

“…This also indicates that acid−base interactions were not a key factor influencing adsorption capacity. In addition, many reports have reported that materials can achieve better results in solid phase extraction through amino modification [41]. Therefore, the strong adsorption affinity is attributed to specific interactions between NH 2 -MIL-101(Fe) and BPs.…”

Herein, we investigated in detail the relationship between surface properties and extraction performance of virgin and amino-functionalized MIL-101s(Fe) for the extraction of 10 bisphenols (BPs) and their derivatives. These BPs were used as model contaminants due to their different hydroxyl groups and contrasting polarities. The differential sorption efficiencies for relatively polar BPs (BPF, BPE, BPA, BPB, BPZ, BPAP and BPP) lies in the formation of hydrogen-bonding between eOH of target analytes and eNH 2 of two MIL-101s(Fe). However, the surface properties of MIL-101(Fe) and NH 2 -MIL-101s(Fe), such as S BET and pore structure, determined the extraction recoveries for BPs derivatives (BADGE, BADGE•2H 2 O and BFDGE•2H 2 O) due to lack of eOH in their molecular structures. NH 2 -MIL-101s(Fe) nanosorbent was successfully applied to the preconcentration/extraction of trace BPs and their derivatives by dispersive solid-phase extraction (DSPE) method. Following optimization of the main factors, recoveries for BPs ranged from 90.8 to 117.8% and their LODs were 0.016-0.131 μg L −1 in environmental waters. Experimental precisions based on relative standard deviations were 0.9-4.9% for intra-day and 1.3-7.6% for inter-day analyses, respectively. These findings provide important information on how to design and modify nanosorbents for highly efficient extraction of pollutants having contrasting polarities. Moreover, the newly developed NH 2 -MIL-101s(Fe)-based DSPE method has a good application prospect in pretreatment of trace pollutants in real-world waters. toxicity than BPA [2][3][4]. The occurrence and distribution of BPA in various environmental matrices and human samples, such as air, surface water, waste water, sewage sludge, aquatic sediments, house dust, foodstuffs, urine, blood, and human breast milk, have been widely documented in the scientific literature [5][6][7]. Additionally, bisphenol analogues and derivatives in personal care products (PCPs), foodstuffs and a variety of environmental matrices, including indoor dust, sediments, fresh and sea waters, sewage effluent and sludge, have been extensively documented [8]. For example, BPF was the most abundant bisphenol analogue in surface waters from sites in Japan, Korea, and China, contributing > 70% of total BP concentrations [9]. This may reflect high usage of BPF as a BPA replacement in southeastern Asia. Similarly, BPF was found as the second most abundant BP analogue in a

“…Thus, careful monitoring and determination of tartrazine in food products is essential for protecting and safeguarding public health. Conventional methods generally employed for tartrazine quantification in food products include high-performance liquid chromatography (HPLC) [ 4 , 5 , 6 ], electrophoresis [ 7 , 8 ], and spectrophotometry [ 9 ]. While these methods offer the required sensitivity and selectivity for the effective analysis of samples with complex matrices, they are often time-consuming and require the use of organic solvents and substantial human resources.…”

This study presents a new optical sensor for tartrazine (TAR) quantification developed using a molecularly imprinted polymer (MIP) as the recognition element, with optical fiber serving as the supporting substrate. The fiber surface was functionalized with 3-(trimethoxysilyl)propyl methacrylate (MPS), and the fiber was coated with MIP using the precipitation polymerization method. The analysis of MIP immobilization on the functionalized optical fiber (FF) was conducted through the use of scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. Experimental parameters, such as contact time and fiber length, were adjusted in order to obtain the highest sensitive response signal for the functionalized optical fiber (FF-MIP). The fiber sensor, FF-MIP, exhibited a relatively higher response signal for tartrazine compared to other interfering dyes. The rapid and total desorption of the analyte from FF-MIP allowed the immediate reemployment of FF-MIP, which also presented an acceptable repeatability for the reflectance signal. The imprinting factors for the studied dyes were between 0.112 and 0.936 in front of TAR, 1.405, and selectivity factors were between 1.501 and 12.545, confirming the sensor selectivity. The FF-MIP sensor was successfully applied for tartrazine quantification in real water samples, where it yielded satisfactory results comparable to those of the HPLC reference method.
