摘　　要：建立一种测定噻菌灵的荧光分析新方法。铽(Ⅲ)为弱荧光物质,噻菌灵的加入对其荧光强度有显著的增强效应。实验结果表明,荧光增强值ΔF与噻菌灵的浓度在2—200nmol/L内呈良好的线性关系,r=0.9970,检出限为0.83nmol/L。本法用于实际样本中噻菌灵的测定,结果令人满意。A novel method of fluorescent spectrophotometry to determine the content of thiabendzole was developed. Terbium was a weak fluorescent material, the fluorescence intensity can be enhance by adding the thiabendzole. The fluorescent enhancement value AF was linear with thiabendzole contents in the range of 2-200nmol/L with the detection limit of 0. 83 nM. The method has been applied for determination of thiabendzole in the real samples with satisfactory results.
