摘要
研究了在盐酸介质中以ＫＢｒＯ３－ＫＢｒ紫外分光光度法测定痕量苯酚的条件，在浓度为０．６ｍｏｌ／ＬＨＣｌ，３×１０－５ｍｏｌ／ＬＫＢｒＯ３，５×１０－４ｍｏｌ／ＬＫＢｒ，６×１０－４ｍｏｌ／ＬＫＩ溶液中测定苯酚时，线性范围为０．１０～２．５ｍｇ／Ｌ，表观摩尔吸光系数为１．８９×１０４Ｌ·ｍｏｌ－１·ｃｍ－１，Ｓａｎｄｅｌ指数为４．９８μｇ／ｃｍ２。本法已用于测定废水中苯酚。
n this paper the authors
studied the conditions for the determination of trace phenol by KBrO3KBr and UV
spectrophotometry in the presence of hydrochloric acid.Based on this technique a new method
for the determination of trace phenol was established.It is shown that the linear range and
apparent molar absorptivity and sandell index are 0.102.5mg/L and 1.89104 Lmol-1cm-1 and 4.
98g/cm2 respectively for the determination of phenol in 0.6mol/L HCl ,310-5mol/L
KBrO3,510-4mol/L KBr,610-4mol/L KI solution.This method has been used to determine phenol
in sewage.
