| 中文摘要: |
| 在pH 9.0的KH2PO4-NaOH缓冲液中,Cd2+与溴化钾、邻菲罗啉反应生成多元配合物导致体系共振光散射强度增大,在λ = 470.3 nm处共振光散射增大程度与镉的浓度有良好的线性关系.方法线性范围为：0.04～2.68 μg/mL,检出限为1.28×10-2 μg /mL,相对标准偏差为0.98％和1.68％,样品加标回收率为91.8％～104.7％. |
| 英文摘要: |
| A new resonance light scattering method for determination of trace cadmium has been studied in the KH2PO4-NaOH buffer solution at pH 9.0 and in the presence of CTMAB.Under the selected conditions,the enhancement of resonance light scattering (RLS) at 473.0nm was linear to the concentration of Cd2+ ranging from 0.04～2.68 μg/mL.The detection limit was 12.8 ng/mL and the RSD were 0.98％,1.68％respectively.The recovery were 91.8％～104.7％. |
