摘要
本文研究了铝－氟－１，５－二（２－羟基－５－磺基苯基）－３－氰基甲（ＤＳＰＣＦ）的显色反应。在硼酸－硼砂介质中，显色反应灵敏，最大吸收波长为６１０ｎｍ，配合物的表现摩尔吸光系数５．０×１０４，铝含量在０－１５μｇ／２５ｍＬ符合比尔定律。该法用于地下水中微量铝的测定获得了满意结果。
The conditions of color reaction of alumininm-flourine-DSPCF complex are investigated in the mediun of H3BO3-Na2B4O7. The spectrophotometric determination method of aluminium is presented. The λmax is 610nm, apparent molar absorptivity reached 5. 0×104. Beer' s law is obeyed in range of 0-15μg/25mL for Al. The method is proved to be satisfactory for determination of microamounts aluminium in groundwater.
