生活废水中悬浮物对挥发酚测定的影响及其消除

Impact of Suspension in Sanitary Sewage on Determination of Volatile Phenol and Its Elimination

针对用 4 -氨基安替比林直接光度法测定未经处理的生活污水中 ,预蒸馏后仍有悬浮物存在这一现象 ,进行了预处理后蒸馏和预蒸馏后用中速定量滤纸过滤的对比实验。

Using 4-amidopyrin direct photometry to determine distreated sanitary sewage, the suspension is still existed after predistillation. The contrast tests, distillation after pretreatment and filtering by quantitative filter paper after predistillation at the medium speed, are done The results show that distillation after pretreatment and filtering after predistillation can all eliminate suspension.
