“…According to U.S. Environmental Protection Agency (EPA), maximum ion content of Cu (II) in industrial waste is 1.3 mg/L. 3 The presence of high concentrations of Cu (II) metal ions in the body can lead to health problems and even death. 4 Some methods employed to reduce the Cu (II) metal ions in wastewater are included chemical precipitation, ion exchange, coagulation, and adsorption 4 .…”

The utilization of bekonang clay and andisol soil composite as the adsorbent of Cu (II) metal ion has been studied. The aims of this study were to determine the optimum conditions of adsorption including pH of the copper solution, adsorbent calcination temperature, composite composition, adsorbent contact time, and their adsorption capacity in metal craft wastewater. Bekonang clay was activated with 1.5M H2SO4 and andisol soil with 3M NaOH. Experiment of adsorption on Cu(II) metal ion was performed at pH solution of 1, 2, 3, 4, 5, 6, 7, and 8, calcination temperature of 100, 200, 300 and 400 °C, variation of composition bekonang clay and andisol soil composite of 100:0, 25:75, 50:50, 75:25, and 0:100 (w/w) and contact time of 15, 30, 60, and 90 minutes in the batch system. Measurement of final concentration at equilibrium was conducted using AAS. The optimum condition of copper(II) metal ion adsorption was obtained at pH 6, calcination temperature 400 °C, bekonang clay and andisol soil composition 25:75 (w/w), contact time 30 minutes with adsorption capacity by 0.37 mg/g. Adsorption isotherm followed Langmuir and Freundlich isotherm. Adsorbent adsorption capacity in the metal crafts wastewater was 17.38 mg/g.

“…Due to its non-toxicity, eco-friendliness, high availability, low cost and good adsorption properties, chitosanbased materials have been increasingly used as biosorbents for pollutants removal from wastewaters, such as dyes [10], fluoride [11], Cr(VI) [12], Hg(II) [13], Cu(II) [14], Pb(II), Cd(II) and Ni(II) [15], As(III) [16] and others [17,18]. Besides, the incorporation of electropositive metal with chitosan can enhance the selectivity and adsorptive properties of the biosorbent for those above contaminants.…”
