Abstract
K oxalate is a convenient deleading reagent for use in clearing plant extracts. It is recommended that a quantity of K-oxalate crystals, estimated to be 0.2-0.5 gm. in excess of the quantity necessary to remove the Pb from the solution being cleared, be placed in a beaker and the cleared solution be filtered on to the crystals. This method insures rapid de-leading, and the high initial concentration of oxalate coupled with the time required to filter and wash the clearing precipitate allows for a partial crystallization of the Pb oxalate, so that it may be rapidly filtered and washed.This publication has 1 reference indexed in Scilit:
