The Liquid-Liquid Extraction of Toxic Metals (Cd, Hg and Pb) by Calixarenes

The Liquid-Liquid Extraction of Toxic Metals (Cd, Hg and Pb) by Calixarenes

Toxic metals (Cd, Hg and Pb) are mostly present in the environment due to natural phenomenon and human activities as well. Exposure of these non-essential elements in the environment causes severe effects. They are known to cause problems in humans as well as in aquatic life. In this work, we demons...
