【摘要】 基于硫离子对罗丹明B 过氧乙酸 NaOH化学发光有较强的增敏作用,建立了流动注射化学发光增强法测定痕量硫的新方法。该法的线性范围为3.0×10-8～8.0×10-7g/mL,检出限为3.5ng/mL,相对标准偏差为2.2%(1.0×10-7g/mLS2-,n=11)。此法已用于环境水样中痕量硫的测定。更多还原

【Abstract】 A chemiluminescence enhancement method for the determination of trace sulfide based on RBCH3CO3HNaOHS2- system was established. The linear range for S2- was 3.0×10-8～8.0×10-7 g/mL with the detection limit of 3.5 ng/mL. The relative standard deviation (n=11) was 2.2% for 1.0×10-7 g/mL S2-. The method was applied satisfactorily to the determination of S2- in environmental water samples.更多还原
