A procedure was developed for the determination of Cu, Mn, Pb, Cd, Co, Cr, and Zn in water samples by Inductively Coupled Plasma–Optical Emission Spectrometry (ICP‐OES) after preconcentration on synthesized 2‐propylpiperidine‐1‐carbodithioate supported by Borassus flabellifer Inflorescence (BFI). The sorbed element was subsequently eluted with 0.4 M HNO 3 , and the acid eluates were analyzed by ICP‐OES. The influence of various parameters such as pH, flow rate of sample, eluent concentration, volume of the sample, and volume of eluent were investigated. Under the optimal conditions, Cu, Mn, Pb, Cd, Co, Cr, and Zn in aqueous samples were concentrated ca. 100‐fold. Recoveries were obtained by the proposed method in the range of 97.8–99.9%. This method was also applied for the analysis of spiked, natural waters and soil samples. The results provide strong evidence to support the hypothesis of an adsorption mechanism.
