摘　　要：研究了标题化合物共振光散射的增强效应。在pH为4.5的酸性介质中,纳米银-十二烷基磺酸钠在350 nm处共振光散射增强与6-苄氨基嘌呤浓度呈线性关系,据此建立了一种测定6-苄氨基嘌呤的共振光散射法。测定的线性范围为2.0×10-8～1.0×10-5mol/L,检出限为2.8×10-9mol/L。该法简便、快速、选择性好、灵敏度高,用于合成样品中6-苄氨基嘌呤的测定,结果满意。The resonance light scattering（RLS） enhancing effect of 6-BA-nanoAg-SDS was studied in HAc-NaAc（pH 4.5） buffer.6-BA can enhance the RLS intensity of nanoAg-SDS system.Under optimum conditions,the calibration graph for 6-BA was obtained,the enhanced intensity of RLS at 350 nm was in proportion to the concentration of 6-BA in the range of 2.0×10-8～1.0×10-5 mol/L.The detection limit（S/N=3） was 2.8×10-9 mol/L,and the results for the determination of 6-BA in synthetic samples was good.
