Abstract: COUMARIN (1,2 BENZOPYRONE) IS COMMONLY USED AS A LEVELER IN VARIOUS ACID NICKEL ELECTROPLATING BATHS, WHERE, DURING ELECTROLYSIS, THE COUMARIN UNDERGOES ELECTROCHEMICAL REDUCTION TO HYDROCOUMARIC ACID (2 HYDROXY PHENYL B PROPANIC ACID). AS THE CONCENTRATION OF HYDROCOUMARIC ACID IN THE BATH INCREASES, THE QUALITY OF THE NICKEL DEPOSIT IS ADVERSELY AFFECTED. THE PRESENT INVENTION DEALS WITH A METHOD OF REMOVING THE HYDROCOUMARIC ACID BY PASSING THE PLATING BATH SOLUTION THROUGH A BED OR COLUMN FILLED WITH A POLYMERIC SORBANT WHICH SELECTIVELY REMOVES THE HYDROCOUMARIC ACID AND COUMARIN FROM THE BATH. THE BED OR COLUMN IS THEN WASHED WITH AN ALKALINE MATERIAL SUCH AS NA2CO3 TO SELECTIVELY REMOVE THE HYDROCOUMARIC ACID FOLLOWED BY WASHING WITH A SOLVENT SUCH AS WARM WATER OR AN ORGANIC MATERIAL SUCH AS A LOW MOLECULAR WEIGHT ALIPHATIC ALCOHOL, ETHER AND KETONE IS DISSOLVE AND RECOVER THE COUMARIN. THE POLYMERIC SORBANT IS PREFERABLY NONIONIC AND IS TYPICALLY IN THE FORM OF SAMLL POROUS BEADS, EACH BEAD COMPOSED OF A LARGE NUMBER OF MICROSPHERES. THE METHOD IS ALSO APPLICABLE TO DERIVATIVES OF COURMARIN AND THE CORRESPONDING REDUCTION PRODUCTS THEREOF.
