摘要
用分光光度法替代“滴定法”测定白土的吸蓝量,对测定过程中的主要影响因素(亚甲基蓝加入总量、缓冲液加入量、煮沸时间、吸附时间等)进行了实验研究,表明分光光度法测定白土吸蓝量是可行的。
Photometry was used to replace 'burette methed' to determine the amount of methylene blue remained in a water suspension after absorption by activated clay. The influencing factors had been investigated, such as,the adding amount of methylene blue and buffer solution, and the time of boiling and adsorbing. The work condition was pointed out.
