Description
A method of spectrophotometric determination of lead in electrolytic manganese and ferromanganese by use of dithizone was investigated. Using ammonium citrate as a masking reagent for a large amount of manganese and potassium cyanide for other heavy metals, lead in electrolytic manganese was determind by dithizone extraction method without separation. But in the case of ferromanganese,lead in the sample solution was separated from iron and manganese by dithizone extraction, and then the lead dithizonate was shaken with dilute acid to transfer lead to the aqueous phase. After bringing the solution to the suitable pH by adding ammonium hydroxide, together with cyanide, the lead in the aqueous phase was determined with dithizone.
