凹凸棒石黏土脱色力的测试

Testing on Decolorization Ability of Attapulgite Clay

摘要: 针对凹凸棒石黏土脱色力测试过程中实验条件难统一、影响因素多而复杂、测试结果误差大、现有测试方法规定不明确等现状，结合甘肃省某地凹凸棒石黏土脱色力的测试，通过一些条件实验，提出了较为合理的测试方法。国家标准物质测试结果与标准值相符，方法精密度（RSD，n=6）小于2％。

Abstract: In the process of decolorization ability testing for Attapulgite clay, the experiment conditions are difficult to unify and the influencing factors are multiple and complex. The errors of the testing results are significant and the present test methods ar
