| 摘 要： | 在NaOH介质中,铁氰化钾氧化鲁米诺产生化学发光,甲萘威对该发光反应有较强的抑制作用且抑制发光强度与甲萘威的浓度呈较好的线性关系,基于此性质建立了测定甲萘威的新方法。在实验的优化条件下,测定甲萘威的检出限为5.5×10-11mol.L-1,线性范围为1.5×10-10—4.0×10-8mol.L-1,对5.0×10-9mol.L-1甲萘威进行了11次平行测定,其RSD为1.74%。该法用于合成样品中甲萘威的测定,结果令人满意。

| Abstract: | A new flow injection chemiluminescence method for determination of carbaryl was developed based on the quench effect of carbaryl on the chemiluminescence reaction between luminal and K_3Fe(CN)_6 under alkaline condition.The emission intensity can be weakened greatly by carbaryl.The chemiluminescence intensity was proportional to carbaryl concentration in the range of 1.5×10~(-10)-4.0×10~(-8)mol·L~(-1) with detection limit of 5.5×10~(-11)mol·L~(-1) The relative standard deviation was 1.74%(n= 11) for 5.0×10~(-9)mol·L~(-1) carbaryl.The method was applied to the determination of carbaryl in synthetic samples with satisfactory results. |
