EXTENDED ABSTRACT The removal of chromium from water and wastewater has caused increased research interest in recent years. Chromium exists in the environment mainly in one of two valence states: a) trivalent Cr(III), and b) hexavalent Cr(VI) form. Cr(VI) enters the environment primarily through industrial processes including the production of steel and metal alloys, chrome plating, dyes and pi...

With the rapid development of printed circuit board (PCB) industry, problem release tetrabromobisphenol A (TBBPA) during PCB manufacturing processes was recognized and harmful to receiving water body. In this study, TBBPA generation paths, fates in industrial wastewater were analyzed. Gas chromatograph-mass spectrometer (GC-MS) scanning results showed that raw materials including solder mask in...

introduction with the rapid development of industries such as metal plating facilities, mining, fertilizer producing industries, tanneries and paper industries heavy metals enriched wastewaters are directly or indirectly discharged into the environment. zinc is a trace element that is essential for human health. it is important for the physiological functions of living tissues and regulates man...

The biomass of Aspergillus flavus was modified by calcium chloride to achieve a bioadsorbent for treating nickel, cobalt, and zinc ions from aqueous solutions. The information of pH, bioadsorbent dose, contact time, and temperature effect on the removal efficiency are presented. The data of Freundlich and Langmuir isotherm and pseudo-first-order and pseudo-second-order kinetic models are also d...
