摘　　要：本文采用了7mW He-Ne激光的单光束热透镜装置测定水中含氟量,检测限为2.2×10^(-7)M,比常规的镧-茜素络合剂比色法的灵敏度提高一个数量级。In this paper, the fluoride ion content in water was determined by the singls beam apparatus with 7 mW He-Ne Laser induced thermal lens.The detection limit of this method was 2.2 ×10-7M. This sensitivity is about 10 times higher than the conventional Colorimetry of Lanthanum Nitrate-Alizarin Complex Compound.
