Cr(VI) has posed great threat on environmental safety and human health, thus the remediation of Cr(VI) pollution is of considerable importance. The adsorption of Cr(VI) from aquatic solution using activated carbon was studied in this paper. The Cr(VI) sorption was relative to pH, contact time, initial content of solution, adsorbent dose and temperature. The maximum removal efficiencies of Cr(VI) were...
The adsorption of Cu2+ from pharmaceutical wastewater by zeolite was studied in a batch adsorption system. Factors influencing copper adsorption such as pH (1-5), adsorbent dosage (5-50 g/L) and contact time (20-600 min) were investigated. The equilibrium of adsorption process was established in about 480 min, while pH was 5 and adsorbent dosage was 30 g/L. After the adsorption equilibrium was achieved,...
