Hexavalent Chromium Removal from Electroplating Waste Using Biochitin from L.Vanamme Shrimp Shell Waste
The increasing number of electroplating industries in this globalization era has a negative impact on the environment because of its liquid waste containing high concentrations of hexavalent chromium, Cr (VI). To overcome this problem, biochitin extracted from white shrimp shell waste (L.vanamme) ha...
