【摘要】 本文研究了毛发锌直接快速测定的锌试剂光度法。该法取消化后的样品溶液直接进行锌的测定，不需反复萃取及分离杂质。锌在０～２０μｇ／１０ｍｌ范围内有直线关系。样品加标回收率为９９％～１０３％。更多还原

【Abstract】 A rapid and direct method for spectrophotometric determination of zincion hair with zinceo is studied. Zinc is di rectly determined in sample solution without solvent extraction or interference seperation The linear range of zinc is 0～ 20 g/10ml. and the recovery of standard addition is from 99 % to 103 %.更多还原
