洗剂液性质对皂石铝柱柱撑效果的影响
Influence of Detergent on Preparation of Al Pillared Saponite
摘要
Abstract
Na-type saponite was synthesized by a hydrothermal method and the saponite samples were washed by deionized water, acid solution, ammonium solution and salt solution, respectively, to obtain Al-pillared saponite. Effect of detergent on the phase and element composition, pore structure, specific surface area and the recovery of Al-pillared saponite samples was investigated. The results show that the alkali species on saponite are removed through simply washing by deionized water and the recovery of saponite is only 80%, and the high pH value is harmful to the structure of Al?O group, causing a lower efficiency of Al pillaring. The recovery rate of saponite washed by acid solution, ammonium solution and salt solution is 100 %. The Al-pillared saponite washed by acid solution has a greater specific surface area of 348 m2/g and Na2O residual amount is only 0.03%.关键词
