摘要
该文介绍了一种快速检测三氯乙烯酸碱度的指示剂,指示剂由盐酸、蒸馏水、溴甲酚绿或甲酚红组成,并将酸碱中和反应同指示剂变色相结合。实践表明,通过盐酸调节指示剂的变色范围,蒸馏水萃取、酸碱中和反应、指示剂变色三者的有机结合,能及时监控三氯乙烯酸碱度变化,适合生产作业间的快速检测。
This paper introduces a kind of rapid detection of trichloroethylene pH indicator. The indicator from hydrochloric acid and distilled water, bromoeresol green or cresol red composition, and acid and alkali reaction with the indicator discoloration combined. Practice shows that through hydrochloric acid to adjust the color range of the indicator, distilled water extraction, acid and alkali neutralization reaction, organic combination of indicator discoloration, timely monitoring trichloroethylene ph change, suitable for rapid detection of production operation.
