摘　　要：采用自制的便携式水质分析仪配合快速检测试剂,可以简便快速地测量Cr(Ⅵ)、磷酸盐等多种水质指标,吸光度与浓度的线性度可达0.99,RSD<5%。国标法标准实验与实际河流水样检测实验对比,t检验验证说明,二者无显著差异。方法适用于城市河流的多参数水质快速检测。Rapid detection of water quality has an important meaning for the protection and management of city river. Rapid detection methods for water quality using portable water quality analyzer made with rapid detection reagent were proposed in this paper,and hexavalent chromium phosphate and other water quality indicators could be detected. A good linear correlation coefficient of 0. 99 between absorbance and the concentration with RSD less than 5% was obtained. Experimental comparison was performed by the national standard method and the proposed method,and T test showed no significant difference between the two methods. The method is suitable for the rapid detection of multi parameter water quality from city river.
