摘要: Different types of powdered activated carbon, viz. charcoal (PACh), graphite (PG) and three samples (PACI, PACII PACIII) prepared from olive stones generated as plant wastes modified with aqueous oxidizing agents, H2O2, HNO3 (NH4)2S2O8, were separated solution by flotation using oleic acid (HOL) a surfactant. The effects initial temperature, pH the suspension, carbon surfactant concentrations, stirring times presence foreign ions on efficiency investigated. Under optimum conditions, separation was almost complete (~100%). CuII-loaded also examined in absence sulphide activators. Nearly 100% CuII removed at 7 after for 30 min or raising temperature to 30°C higher. In addition, may be quantitatively 3 room if are used activato...
