摘要
《水和废水监测分析方法》中的铬酸钡光度法测定硫酸盐的浓度范围为 8～ 8.5mg L。随着环境样品质量的提高 ,为能测定 0 .2～ 8mg L硫酸盐 ,对该方法进行改进 ,由原来在 4 2 0nm测定改在375nm测定 ,灵敏度提高了 8倍。
Density range of the luminosity method of barium-chromate for measuring vitriol in the supervision analysing method of water and waste water was 8～8.5 mg/L. With the quality of the environmental sample improved,in order to measure vitriol of 0.2～8 mg/L, the condition of original 420 nm was changed to that of 375 nm. As a result,its sensitivity was increased 8 times.
