| Abstract: |
| Using lignite prepared coal-based carbonaceous adsorbents (CBCA) was an efficient adsorbent and it to deal with the simulation of containing arsenic (Ⅲ) from wastewater. Based on the experimental data processing , it concluded that discusses the affecting parameters of adsorption effects such as the solution pH , dosage of adsorbent is n, adsorption time is t, adsorbent particle size is g, initial concentration is C0, solution temperature T . The results indicated that the order of adsorption effect factor value is n>pH>t>M>C0 .Ultimately determine the best conditions of adsorption as follows: pH = 4.0, n is one tons of waste water should be 16 kg of CABC, t=180 min, M=160~200 meshes,C0=3.0 mg/L,T=25℃, and η of the adsorption rates is 98.53%. It’s especially beneficial for people with separate treatment of contains arsenic from industrial wastewater by using this promotion adsorbent. |
