Preparation of magnetic resin microspheres M-P(MMA-DVB-GMA) and the adsorption property to heavy metal ions

Magnetic carbon-coated iron nanoparitcles were employed as adsorbent to study the adsorption characteristics of some metal ions, such as Cr, Ni, Cu, Pb, Zn. The effect of solution conditions such as pH, amounts of adsorbent, the co-existent ions was investigated. The results show that adsorption property of carbon-coated iron particles to heavy metal ions is improved at the condition of treated by H2O2, and at pH 8-9.5, Cr、Ni、Cu、Pb and Zn were retained on 30mg carbon-coated iron nanoparticles after shaking 3 min, and could be eluted by acid solutions(pH=1~2).

Experiment used the microwave and the adjustment of pH to modify corncob to adsorb heavy metal ions (Zn2+, Pb2+) from Water. In order to find out the best adsorption condition on the liquor which concentrations of Zn2+and Pb2+were 30 mg/L respective, the experiment used method of control variables and the modified corncob adsorption rate of Zn2+was the reference index. The results indicated that when corncob diameter, dosage, absorbing time, shaking speed and the pH value of liquor zinc chloride were 1.5mm, 20mg/L, 30min, 180rpm and 6, respectively, the adsorption rate of Zn2+and Pb2+reached the highest by 76.67% and 98.54%. The results showed that modified corncob adsorption rate of Zn2+and Pb2+were more than 80% and 98% at low concentrations. In conclusion, modified corncob had a good adsorption property of heavy metal ions in water.
