Method for Determining D-Xylose in Copper-Plating Solutions

摘要

A modified colormetric procedure for the determination of low concentrations of D-xylose in copper sulfate-sulfuric acid plating baths is described. The D-xylose is added to the copper solutions to eliminate gas entrapment in the finished copper deposit. Determinations were made at 620 nm with concentrations between 0.01 to 0.1 mg D-xylose per ml. The system obeys Beer's Law at these concentrations. (ERA citation 06:020468)
