Separation of trace levels of lead from concentrated-matrix electroless nickel plating (ENP) waste solutions is required to meet the increasingly stringent environmental regulations. This study aimed to develop a solid phase extraction (SPE) system using a molecular recognition technology (MRT) gel for the selective separation of trace levels of lead (Pb) from the waste discharge of ENP operations. The methodology involved the utilization of two SPE-MRT cartridges, AnaLig® Pb-01 and AnaLig® Pb-02, which were tested for their efficiency in lead separation. Subsequent analysis was performed using inductively coupled plasma optical emission spectrometry (ICP-OES) to quantify the lead concentration after extraction. The results indicated that both cartridges achieved effective lead recovery, demonstrating the potential for using MRT in environmental management of heavy metal contamination in plating waste solutions. The study concludes that this method provides a viable solution for meeting environmental standards while effectively managing the disposal of ENP waste solutions.
