Paper Title:
Study on Adsorption Characteristics of Ni (II) by Palygorskite
  Abstract

Adsorption characteristics of Ni (II) by Palygorskite were investigated using a batch adsorption, and the effects of various experimental parameters were discussed. Results showed that the adsorption capacity of palygorskite for Ni (II) increased with increasing contact time and amount of adsorbent. Ni (II) adsorption onto palygorskite was well fitted by the pseudo-first-order kinetic model. Adsorption capacity increased to a maximum as the treating temperature increased to 673K. Heat-activation at 773K resulted in degradation of channel structure and adsorption capacity loss of palygorskite. With increasing HCl concentration of acid treating solution, adsorption capacities for Ni (II) decreased firstly and then increased, a minimum was obtained at 4mol/L of HCl concentration.
