Screening long-time plating effluent qualities by sorbent sorption with XRF analysis.

Long-term monitoring of plating effluent quality traditionally requires dense frequency sampling and analysis for multiple elements are needed. An effective and rapid approach was developed to monitor long-time plating effluent quality. The approach employs the placement of low-cost sorbents (chitosan, zeolite and granular activated carbon) in plating effluents followed by analysis of multiple-element X-ray fluorescence (XRF).
