Adsorption of zinc ion on leonardite prepared from coal waste

Naturally occurring leonardite, obtained from Mae Moh mine lignite, has been tested as a potential sorbent for Zn 2+. The factors that affect to the sorption, such as pH, contact time and the adsorption isotherm were also investigated. The high performance of Zn 2+ removal was demonstrated at pH val...
