“…Heavy metals such as cadmium (Cd) and lead (Pb) pose significant risks to human health, necessitating efficient methods to monitor these metals. − Owing to their sensitivity and selectivity, electrochemical sensors have been widely used for the detection of heavy metals. , The anodic stripping voltammetry (ASV) sensor has been extensively employed for the detection of Cd and Pb. When a Cd- or Pb-containing sample is introduced, the metal ions preconcentrate on the WE surface.…”

Paper-based electrochemical devices (PEDs) have emerged as versatile platforms that bridge analytical chemistry and materials science, demonstrating advantages of portability, cost-effectiveness, and environmental sustainability. This study investigates the integration of a graphene pseudoreference electrode (GPRE) into a PED, and it exhibits potential advantages over the traditional Ag/AgCl pseudoreference electrode (PRE). In addition, the electrochemical properties and stability of GPRE are compared with those of the traditional Ag/AgCl PRE. The results demonstrate that GPRE exhibits a stable and reproducible potential during electrochemical measurement throughout 180 days, demonstrating its suitability as an alternative to an expensive metal PRE. Furthermore, a GPRE-incorporated paper-based device is designed and evaluated for use in the electrochemical detection of cadmium (Cd) and lead (Pb) using an in situ bismuth-modified electrode. The GPRE-incorporated PED exhibited good analytical performance, with a low limit of detection of 0.69 and 5.77 ng mL–1 and electrochemical sensitivities of 70.16 and 38.34 μA·mL·μg– 1·cm–2 for Cd(II) and Pb(II), respectively. More than 99.9% accuracy of the sensor was obtained for both ions with respect to conventional inductively coupled plasma-mass spectrometry. The results highlight the effectiveness and suitability of the GPRE-incorporated PED as a sensor for various applications, such as environmental monitoring, food quality control, and medical diagnostics.

In the present study, ferrihydrite-chitosan nanocomposite (FCN) was successfully produced by co-precipitation method and used for the first time as a recyclable flocculant for pre-treatment of palm oil mill effluent (POME). The physicochemical properties of FCN were studied using Raman spectrometer, Scanning Electron Microscope (SEM) and Thermogravimetric Analyser (TGA). The feasibility of FCN to remove total suspended solids (TSS), turbidity, chemical oxygen demand (COD), and, oil and grease (O&G) from POME was investigated using a jar test method. The optimum conditions for contaminant removal from POME were determined by varying the experimental parameters such as flocculant dosage, solution pH and settling time. The results obtained showed that FCN, at a dosage of 1.5 g/L, a contact time of 60 min and pH of 5.0 gave a highest reduction of turbidity, TSS, COD and O&G levels by 72.38%, 77.32%, 71.60% and 53.40%, respectively. Besides that, FCN exhibited a better flocculation performance as compared to alum and chitosan. After three cycles of flocculation/deflocculation process, FCN retained satisfying flocculation efficiency and flocculants recovery in the range of 80-83% and 43.2-78.6%, respectively. Combination of charge neutralisation and polymer bridging was the main key mechanism of interaction between FCN and POME contaminants. The synergy effect between iron oxide/oxyhydroxide nanoparticle and chitosan has increased the physicochemical properties and flocculation performance of the FCN nanocomposite. Overall, FCN nanocomposite can be used an alternative flocculant for POME treatment.

“…, compounds derived from microbes, plants, and algae) is receiving an alternative consideration over conventional fabricated procedures. 30 The plant extract-based synthesis of D-MgO-NPs is the best method because these may have aldehydes, ketones, acetic and citric acid amides, amino acids, proteins, polysaccharides, and terpenoids, 31,32 which may have properties to act as reducing or capping agents. Thus, the golden dew ( Duranta erecta ) plant has been selected because it contains various phytochemicals, i.e.…”
