SIMULTANEOUS SPECTROPHOTOMETRIC DETERMINATION OF CHLORIDE AND RESIDUAL CHLORINE IN WATER WITH MERCURY THIOCYANATE METHOD
【摘要】 研究了硫酸铁铵 硫氰酸汞间接光度法同时测定水样中微量氯离子及余氯的方法。该法具有较高的选择性及灵敏度 ,测定结果满意
【Abstract】 Simultaneous absorptiophotometric determination of chloride ion and residual chlorine in water with mercury thiocyanate method was studied. Beer′s law is obeyed in the range of 2~100μg/10ml for chloride ion. The method was applied to the determination of chloride ion and residual chlorine in water samples with satisfactory results.
