| 摘 要： | 发现盐酸克伦特罗（Clenbuterol hydrochloride，CLB）对NaIO4氧化曙红Y（R）有显著的催化效应，首次建立了超灵敏催化固体基质室温磷光法（SS—RTP）测定痕量CLB的新方法．该法具有很高的灵敏度（检出限为0．021zg spot^-1，对应浓度为5．2×10—20g ml^-1）与好的选择性（相对误差为±5时，共存离子（物）不干扰），用于猪毛样品中CLB残留量的测定，回收率为98．6-104％．

| Abstract: | It was found that clenbuterol hydrochloride （CLB） had obvious catalytic effect on NalO4 oxidizing cosine Y （R）. Based on this, a new super sensitive catalytic solid suhstrate-room temperature phosphorimetry （SS-RTP） for determination of trace CLB has been established. This method had high sensitivity （detection limit （LD）： 0.021 zg spot^-1, corresponding concentration： 5.2 × 10^-20 g mL^-1） and good selectivity （Er = ±5%, coexistent ions or coexistent materials were of no interference）. It has been applied to the determinalion of residual CLB in the bristle samples. The recovery rate was 98.6-104%. |
