Stellerite-seeded facile synthesis of zeolite X with excellent aqueous Cd2+and Ni2+adsorption performance
文献摘要：
Zeolite X was synthesized by a two-step hydrothermal method using natural stellerite zeolite as the sil-icon seed,and its adsorption performance for Cd2+and Ni2+ions was experimentally and comprehen-sively investigated.The effects of pH,zeolite X dosage,contact time,and temperature on adsorption performance for Cd2+and Ni2+ions over were studied.The adsorption process was endothermic and spontaneous,and followed the pseudo-second-order kinetic and the Langmuir isotherm models.The maximum adsorption capacitiesfor Cd2+and Ni2+ions at 298 K were 173.553 and 75.897 mg g-1,respec-tively.Ion exchange and precipitation were the principal mechanisms for the removal of Cd2+ions from aqueous solutions by zeolite X,followed by electrostatic adsorption.Ion exchange was the principal mechanisms for the removal of Ni2+ions from aqueous solutions by zeolite X,followed by electrostatic adsorption and precipitation.The zeolite X converted from stellerite zeolite has a low n(Si/Al),abundant hydroxyl groups,and high crystallinity and purity,imparting a good adsorption performance for Cd2+and Ni2+ions.This study suggests that zeolite X converted from stellerite zeolite could be a useful environmentally-friendly and effective tool for the removal of Cd2+and Ni2+ions from aqueous solutions.
