This study reported the feasibility of flushing remediation of Cu contaminated soil using thiacalix arenetetrasulfonate (TCAS) reagent. Batch experiments were performed to test the factors influencing remediation of Cu contaminated soil. The effects of pH value, initial conentration and contact time.on the removal capacities of Cu by TCAS reagent had been studied. The results showed that the TCAS...
Different hazardous chemicals have been introduced in our environment. Heavy metals, like lead is among those. As the earth approximates that of a closed system, such contaminant will freely distribute itself from one sphere to another at an infinite number of years. Street foods and the raw materials used to prepare it may then be laden with lead. The health and safety of the public is thus at stake...
