Abstract:
Low grade phosphorus-containing iron ore (LGPIO), a raw and wasted industrial solid material was used as an adsorbent to remove Cu(II) cation from wastewater. The effects of initial pH value, adsorptive time, initial Cu(II) cation concentration, adsorptive temperature and LGPIO dosage on the Cu(II) cation removal efficiency were studied. The results show that the Cu(II) cation removal efficiencies exceed 99.65% and Cu(II) cation concentrations are less than 0.30 mg/L under the conditions of pH value 6.1, temperature 25oC, adsorptive time 30 min, initial Cu(II) cation concentration 100 mg/L, particle size lower than 0.147 mm, adsorbent dosage 10 g/L and stirring speed 250 r/min. After Cu(II) cation removal reaction, the Cu(II) cation concentrations completely accord with the requirement of national discharge standard of water pollutants for iron and steel industry (GB 13456-2012) (TCu(II)=0.5 mg/L) in China. Therefore, it can be concluded that LGPIO is a new low-cost adsorbent which is suitable for the adsorption of Cu(II) cation from wastewater.
