Abstract
The invention relates to a method of extracting phosphorus from chemical nickel-phosphorus plating waste liquid for preparation of calcium phosphate. The method comprises the following process steps: weighing and putting a certain amount of chemical nickel plating waste liquid in a beaker; adding an excess amount of an oxidizing agent into the chemical nickel plating waste liquid containing Ni<2+>, sodium hypophosphite, sodium phosphate, carboxylate, sodium sulfate or ammonium sulfate, wherein the oxidizing agent may be hydrogen peroxide, hypochlorite, sodium permanganate or potassium permanganate; oxidizing hypophosphite radicals in the chemical nickel plating waste liquid and a by-product of chemical plating phosphite radicals into phosphate radicals; and then adding a sufficient amount of calcium chloride into the chemical nickel plating waste liquid under stirring so as to allow orthophosphate radicals to form precipitate with calcium ions and carrying out filtering after standing for a period of time so as to obtain the precipitate which is a phosphorus-containing substance, i.e., calcium phosphate. With the method provided by the invention, the phosphorus element in the chemical plating waste liquid can be extracted in the form of phosphate; calcium phosphate is prepared by using the nickel plating waste liquid as a raw material, and the advantages of a simple process and low production cost are obtained.
