英文摘要	以分光光度法测定高含量膨润土吸蓝量,应用正交试验设计对分光光度法的实验条件进行优化,确定的最佳实验条件:煮沸时间为5 MIn,4%焦磷酸钠溶液加入体积为20 Ml,0.01 MOl/l亚甲基蓝溶液加入体积为30Ml,振荡时间为15 MIn。该法与滴定法对比,测定值相对误差在4%以内,相对标准偏差为1.04%,可满足高纯度膨润土吸蓝量的分析要求。; Spectrophotometry was used to measure the methylene blue value of high purity bentonite, and the orthogonal tests were used to optimize and determine the optimal experimental conditions: the boiling time was 5 min, 4% sodium pyrophosphate solution was added to a volume of 20 mL, 0.01 mol/L methylene blue solution was added to the volume of 30 mL, shaking time was 15 min.Compared the spectrophotometry to traditional titration analysis, the relative error of the experimental results was less than 4% and the relative standard deviation was 1.04%, which was proved to be accurate and reliable to meet the analytical requirements.; 国家质检总局科技计划项目(2014IK254)
