The polarographic determination of aluminium : The oscillographic polarography of aluminium in calcium chloride solution

A study of the polarography of aluminium using the linear-sweep cathode ray polarograph is described. The conditions nccessasary for obtaining satisfactory aluminium waves in this medium have been established and the relationship between aluminium peak height and concentration examined. The occurrence of unexpected phenomena relating the change of step shape with varying start potential values is described and discussed and a method for overcoming the effects, by buffering, is presented
