Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Journal of Applied Polymer Science, EarlyView.A graphene oxide‐functionalized PEGylated polystyrene (PS‐PEG@GO) resin is developed as a recoverable, reusable adsorbent for cationic dye removal from water. Combining efficient multi‐dye adsorption with simple filtration‐based recovery and stable reuse, it retains over 90% removal for CV and MB and 89.19% and 85.15% for R6G and RB after 20 cycles ...
