“…Analysis of the experimental data suggest that adsorption of ibuprofen can be realized in a wide range of pH, what is determined mostly by the type of the sorption material used. More acidic environment is the most suitable when adsorbing ibuprofen onto activated carbons (Maestre et al 2007;Guedidi et al 2017) as neutral or basic are better one to adsorb it onto natural clays (Martín et al 2019;Rafati et al 2018;Khazri et al 2017). Comparison of maximum sorption capacities of different type sorbents confirmed that the most important is appropriate selection of the material.…”

The aim of presented research concerned synthesis of a novel lignosulfonate-based sorbent and its application in batch adsorption tests related to removal of an active pharmaceutical ingredient (ibuprofen). Obtained hybrid material was thoroughly characterized with respect to morphology, porosity (BET method and BJH algorithm), electrokinetic stability, and characteristic functional groups. As a result of the proposed synthesis route, an active MgO-SiO 2 /lignosulfonate hybrid was obtained as confirmed by significant amount of functional groups present in its structure and relative good parameters of the porous structure (A BET = 71 m 2 /g, V p = 0.2 mL/g and S p = 11.8 nm). Next stage concerned typical batch adsorption tests with respect to active pharmaceutical ingredient (API)-ibuprofen. It was proved that efficiency of removal of ibuprofen was mostly determined by its structure as well as variable process parameters. Affinity of sorption material towards model organic impurity was established based on equilibrium and kinetics study of adsorption process performed. A key element of the investigations was an interaction and mechanism study resulted from interpretation how the parameters of the adsorption affect the nature of the adsorbent/adsorbate interactions. Experimental data collected, supplemented with regeneration tests, proved significant affinity of ibuprofen to the hybrid sorbent and enabled determination of nature of the adsorbent/adsorbate interactions. Moreover, suggested mechanism of ibuprofen sorption was proposed.

Coconut (Cocos nucifera) is a palm tree belonging to the Arecaceae family that possesses a thousand and one uses. Each part of the tree has it's uses and can be made into products. Also, various parts of the coconut tree have been utilized to remove various types of dyes from water and waste water via chemical, physical and biological methods. Adsorption is one of the widely used physical methods over their counterparts owing to cost efficiency and ease in handling. The key parameters for the adsorption process are the initial concentration of adsorbate, dosage of adsorbent, the pH and contact time. Additionally, the kinetic parameters, equilibrium isotherm and thermodynamics of the adsorption of dyes on the adsorbent were explored.

“…Adsorption isotherms models are vital in describing and explaining interactive behavior of adsorbate and the adsorbent (MP-POP) (Bordoloi et al, 2017;Rafati et al, 2018). Therefore, equilibrium studies were carried in order to establish the adsorption mechanism.…”

“…The favoring of Langmuir by the isotherm models indicates that the adsorption was a monolayer adsorption. Dubin-Radushkevish model is normally used to differentiate between chemical and physical adsorption by looking at the mean energy (E) (Bordoloi et al, 2017;Rafati et al, 2018). The focus is on the energy value (E), if the value of energy is <8 kJ mol −1 , then the adsorption was a physical one.…”

In this study, a magnetic porphyrin-based porous organic polymer (MP-POP) nanocomposite was successfully synthesized according previous studies and applied as an adsorbent for simultaneous extraction and preconcentration of four neonicotinoid insecticides from surface river water. The MP-POP was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy/energy dispersive x-ray spectroscopy (SEM/EDS), N 2-adsorption/desorption analysis, Fourier Transform infrared spectroscopy (FTIR). The neonicotinoid insecticides were quantified using high performance chromatography coupled with diode array detector (HPLC-DAD). The MP-POP shown to have a high surface area, highly porous structure and strong affinity toward the investigated analytes. The adsorption capacities were 99.0, 85.5, 90.0, and 79.4 mg g −1 for acetamiprid, clothiandin, thiacloprid and imidacloprid, respectively. The influential parameters affecting the magmatic µ-solid phase extraction (M-µ-SPE) procedure were investigated using fractional factorial design and surface response methodology (RSM). Under optimum conditions, the method exhibited relatively low limit of detection in the range of 1.3-3.2 ng L −1 , limit of quantification in the range of 4.3-11 ng L −1 and wide linearity (up to 600 µg L −1). The intraday and interday precision, expressed as the relative standard deviation (RSD) were <5%. The percentage recoveries for the four target analytes ranged from 91 to 99.3% for the spiked river water samples. The method was applied for determination of neonicotinoids in river water samples and concentrations ranged from 0 to 190 ng L −1 .
