Abstract
1522410 Determining heavy metal ions electro-chemically SIEMENS AG 17 Sept 1976 [25 Sept 1975] 38739/76 Heading G1N Heavy metals in aqueous liquor are determined by conducting the liquor for a predetermined length of time and at a constant flow-rate past a solid electrode maintained at a negative direct voltage to deposit heavy metal thereon, replacing the liquor by an electrolyte and the negative voltage by a positive direct voltage and determining the charge to remove any deposited heavy metal from the electrode. The negative voltage may be – I to -4V preferably – 1À5 to -2À5V, and the predetermined length of time 1-10 minutes. The positive voltage may be 0À5 to 3V preferably 0À8 to 2V. The electrolyte is preferably sodium chloride or sodium sulphate of concentration 10
