| 摘 要： | 污水样品用硼氢化钾片剂酸性氢化反应，使硫化物同酸作用转化为Ｈ２Ｓ，并被氢气吹出，以ＮａＯＨ溶液吸收，再用对氨基二甲基苯胺光度法测定。为了应急监测，研制了ＬＳ－１型硫化物快速测试预装置，配用ＤＲ／２０００型便携式分光光度计，可在现场进行了水中硫化物的快速监测。．

| Abstract: | With KBH 4 acidic solution, sulfur was transformed to H 2S and blew out. After absorption of H 2S with NaOH, sulfur was determined by spectrophotometry. For accidental determination of sulfur, pretreatment device LS 1 was designed. Attached to DR/2000 portable spectrometer, the device was used in field determination of sulfur in waste water. |
