摘要
对通用硅酸盐水泥不同品种及同一品种不同含量水泥与水泥熟料进行水溶性铬(Ⅵ)的试验,分别从试验过程和仪器性能两方面进行研究,着重分析滤液颜色、酸度、显色剂、显色时间、滤液放置时间及仪器测定等因素对测定结果的影响,提高数据准确性和精确性.
Experiments on water-soluble chromium(Ⅵ)of different kinds of general Portland cem ent,the same type of cement with different content and cement clinker were carried out.The research was carried out from two aspects of experimental process and instrument performance,focusing on the analysis of the influence of filtrate color,acidity,color developing agent,color developing time,filtrate placing time and instrument measurement on the test results,so as to improve the accuracy and precision of data accuracy.
