摘　　要：采用luminal-KMnO4体系化学发光法,对水中微量偏二甲肼的含量进行了测定,分别考察了pH值、鲁米诺浓度、高锰酸钾浓度、载流速度以及载流管长度对发光强度的影响,确定了最佳试验条件,并在此条件下得出偏二甲肼标准含量曲线,其线性范围为1.0×10^-6-1.0×10^-5g/L,检出限为1.0×10^-7g/L。The luminal-potassium permanganate chemiluminescent system was used in the measurement of tiny unsymmetrical dimethyl hydrazine（UDMH） in water, and the respective experiment was carried out to ascertain the influence of PH, thickness of luminal and potassium permanganate, carrying velocity and the length of carrying pipe on the relative luminescence intensity. The optimal experimental condition was determined based on these experiments and the standard curve of UDMH was worked out, with its linearity range being 1.0×10^-6-1.0×10^-5 g/L. The detection limit of this method was 1.0×10^-7 g/L.
