Abstract This study investigates the potential of utilizing spent coffee grounds (SCG) treated with Ca(OH) 2 as an adsorbent for removal lead (Pb(II)) ions from aqueous solutions. The SCG was subjected to sequential treatments, including washing, drying, sieving, and immersion in solutions varying concentrations. Adsorption experiments were conducted under different conditions evaluate efficiency adsorbent, variations contact time, solution pH, dosage, temperature, initial Pb(II) ion...
Abstract In this study, nanocomposite membranes based on bacterial cellulose (BC) and graphene oxide (GO) were synthesized at different volume ratios of BC to GO. The mechanical properties these investigated determine the optimal combination ratio. Furthermore, adsorption capacity for Cr(VI) heavy metal ions was evaluated under various conditions, including time, temperature, pH, stirring rate, adsorbent dosage. strength analysis revealed that membrane with a GO ratio 1:6 exhibited highest...
Abstract In this study, the effect of alkaline‐treated spent coffee grounds and compatibilizer on mechanical properties bio‐composite based polypropylene (PP) matrix was investigated. After alkaline treatment, surface became rougher; hence PP could better adsorb encapsulate treated compared with that untreated ones. The TGA analysis shows had thermal than When increasing weight percentage from 10 to 20, tensile strength flexural PP‐based composite decreased. These containing were enhanced...
