摘要
目的：建立一种不需消化快速、准确测定尿锌的方法。方法：双硫腙四氯化碳法直接测定尿中锌。结果：线性范围0．04～2．0μg/ml，回归曲线Y=1．26X-0．0075，相关系数r=0、9998，变异系数小于5％。结论：双硫腙四氯化碳法直接测定尿中锌方法简便、灵敏可靠，适合临床应用。
Objective：To establish direct photometry which is convenient, sensitive and need not pretreat,nent. Methods：Zinc in Human urine was detected with dithizone in carbon tetrachloride. Results： The linear range was 0. 04 - 2. 0 μg/ml, the linear regression equations was Y = 1.26X- 0. 0075, coefficients of correlated r = 0. 9998, the coefficients of variation （cv） 〈 5%. Conclusion：Direct photometry with dithizone in carbon tetrachloride is convenient, sensitive and reliable to detect zinc in hunam urine, suitable for clinical application.
