One-pot synthesis of ion-imprinted three-dimensional porous material based on graphene oxide for the selective adsorption of copper(II) J. Environ. Sci. Health Part A (IF 2.1) Pub Date : 2023-04-09 Zhifeng Xu, Lizhen Li, Junhua Li, Peihong Deng
Abstract Molecularly imprinted polymers (MIPs) are synthetic polymers with predetermined selectivity for a given analyte. One major problem associated with MIPs is the inaccessibility of a large fraction of the recognition sites that remain buried within the polymeric matrix. To address this problem, the high selectivity imparted by the imprinting technique and the porosity of three-dimensional (3D)

Biosorption of cadmium from aqueous solution by combination of microorganisms and chitosan: response surface methodology for optimization of removal conditions J. Environ. Sci. Health Part A (IF 2.1) Pub Date : 2023-04-10 Elham Khanniri, Mojtaba Yousefi, Amir Mohammad Mortazavian, Nasim Khorshidian, Sara Sohrabvandi, Mohammad Reza Koushki, Saeideh Esmaeili
Abstract The food-grade adsorbents of Saccharomyces cerevisiae (108 CFU/mL), Bifidobacterium longum (108 CFU/mL) and chitosan (1%w/v) alone or in combination were used for biosorption of cadmium (Cd) from aqueous solution. Among the tested adsorbents, combination of B. longum and chitosan had the highest efficiency. Therefore, biosorption process with B. longum/chitosan as the most efficient biosorbent

Synthesis of the MnO2-Fe3O4 catalyst support on amorphous silica: a new Fenton’s reagent in the degradation of the reactive blue-19 in aqueous solution J. Environ. Sci. Health Part A (IF 2.1) Pub Date : 2023-04-06 Nguyen Manh Ha, Tran Thi Huong, Ninh The Son
Abstract In this study, a new Fenton’s reagent was synthesized via two steps: (1) the dispersed Fe3O4 nanoparticles were immobilized on the surface of the SiO2 carrier via the precipitation process, and (2) the MnO2 nano-sheets were coated on the surface of Fe3O4/SiO2 via hydrothermal method. The SiO2 carrier has been synthetically utilized from Vietnamese rice husk. The successful formation of the

Biosorption of toxic metal ions (Cr+6, Cd2+) and nutrients (PO43-) from aqueous solution by diatom biomass J. Environ. Sci. Health Part A (IF 2.1) Pub Date : 2023-04-05 Nsovo Mhlarhi, Wilson Mugera Gitari, Wasiu Babatunde Ayinde, Nikita Tawanda Tavengwa, Rabelani Mudzielwana, Oisaemi Uduagele Izevbekhai
Abstract This paper evaluates diatom biomass as a biosorbent for removing Cr+6, Cd2+, and PO43- ions from water. The diatom was characterized by X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), and Scanning Electron Microscopy (SEM-EDS) for its crystallinity, functional groups, and morphology. A batch sorption study was conducted to evaluate the parameters influencing Cr+6, Cd2+, and PO43-

Comparative physicochemical analysis of galvanic sludge wastes J. Environ. Sci. Health Part A (IF 2.1) Pub Date : 2023-04-05 Ana S. Stojković, Nenad S. Krstić, Dragan M. Đorđević, Marija Milivojević, Ivan M. Krstić
Abstract The paper provides the physicochemical analysis of galvanic sludge to determine the presence and concentration of toxic metals. Two sludges sampled from the same factory, but from different technological processes, alkaline galvanic sludge obtained from galvanizing process and acidic sludge generated from the chromium plating process were analyzed.
