研究了在醋酸缓冲介质中,盐酸羟胺还原Cu~(2+)定量所形成CuSCN的共振散射光谱。确定了散射光强度与溶液中盐酸羟胺浓度的关系。提出了共振散射法测定盐酸羟胺的新方法。方法的检出限为0.04μg/mL,线性范围为0.04—0.80μg/mL。方法用于工业品盐酸羟胺的测定,结果满意。
The resonance scattering spectra of CuSCN formed by reduction of Cu ~ (2+) with hydroxylamine hydrochloride in acetate buffer medium were studied. The relationship between the intensity of scattered light and the concentration of hydroxylamine hydrochloride in solution was determined. A new method for the determination of hydroxylamine hydrochloride by resonance scattering was proposed. The detection limit of the method was 0.04μg / mL with a linear range of 0.04-0.80μg / mL. The method was applied to the determination of hydroxylamine hydrochloride in industrial products with satisfactory results.
