摘要
Abstract
Stabilization of chrome shavings can effectively reduce chrome pollution.In this study,Ca (OH)2 was used as stabilizer.Orthogonal experiments were used to investigate the effects of various factors on the stability of chrome shavings,such as Ca (OH)2 dosage,temperature,constant temperature time and water content.We determined the stabilization effect by detecting the leaching solution of Cr (Ⅵ) and Cr (Ⅲ) content.The optimum condition is as follows:the usage of Ca (OH)2 is 4％(based on the dry weight of chrome shavings),H2O is 70％,the ignition temperature is 300 C and the reaction dme is 45min,the stabilizing effect of chrome shavings is the best.meanwhile,simultaneously,the mass of leather shavings was reduced by 13.2％.关键词
