This study is likely to assess the pollution grade of the Cikapundung River in Bandung city and the extent to which river water is exposed to heavy metals hence, the safety levels of water users. This research aimed to synthesize and apply the adsorbent AXAD-16-DPC chelating resin to copper and lead-containing solution. To determine dissolved heavy metal (Cu and Pb ions) levels in the water Cikapundung River using laboratory instruments to pre-concentrate the sample using a solid-phase extraction method. Analysis of heavy metals in the water sample was carried out using flame atomic absorption spectrometry (FAAS) Solidphase extraction was used to pre-concentrate trace metal as it attains a high concentration factor, and potentially interfering matrices may be removed. The clear route is based on the retention of the targeted analytes on a mixed chelating organic ligand, 1,5-diphenyl carbazide (DPC) with polystyrene-divinyl benzene, a co-polymer Amberlite XAD-16 resin matrix placed inside cartridge column tube. The composite chelating resin was found to be successful as it can adsorb Cu (II) and Pb (II) ions with a high percentage of recovery around 101.20% for Pb (II) and 96% for Cu (II), and the reusability of resin is possible as RSD <5%. Fourier transform infrared (FTIR) spectroscopy was used to characterize the chelating resin, and 2 M Nitric acid was the best eluent. Moreover, water quality properties in terms of its physicochemical parameters assessed were Temperature (24.67 C), pH (7.66) of sample solution, Conductivity 259 ɱS/cm), Turbidity (130) and DO (3.80 mg/L).
