摘　　要：基于咪唑啉衍生物2-十七烯基-N-氨乙基咪唑啉在氨水NH4Cl介质中产生的阴极波,拟定了该化合物的定量测试方法。在0.004mol/LNH4Cl和0.196mol/L氨水(三次去离子)底液中,该阴极波二阶导数峰电流与2十七烯基N氨乙基咪唑啉浓度在5.0×10-5～1.0×10-4mol/L范围内呈线性关系,线性回归系数0.9996。平均回收率为99.7%,相对标准偏差为3%。可以用于日常生产的质量控制。In the presence of the cathodic wave that is produced from 2-heptadecenyl-N-aminoethylimidazoline in ammonia-NH_4Cl solution. A new quantitative analysis method for direct determination of 2-heptadecenyl-N-aminoethylimidazoline was proposed. In 4.0×10^(-3)mol/L NH_4Cl and 0.196 mol/L ammonia buffer solution, peak current of the cathodic wave is proportion to 2-heptadecenyl-N-aminoethylimidazoline with concentration in the range of 4.0×10^(-5)~1.0×10^(-4)mol/L, and the linear regression coefficient is 0.9996.Average recovery is 99.7%,relative standard deviation is 3%. It may be used to control quality in daily production .
