Adsorption behavior and mechanism of amino methylene phosphonic acid resin for Ag(Ⅰ) Shu Zeng-Nian(舒增年)1, Xiong Chun-Hua(熊春华)2, WANG Xu(王 旭)1 1. Department of Chemistry, Lishui.... The apparent activation energy of adsorption, Ea is 22.8 kJ/mol, the enthalpy change (?H) of sorption is 17.4 kJ/mol. The adsorption mechanism shows that the functional group of APAR coordinates with Ag......
