【摘要】 对海泡石处理含铬废水进行了试验研究,结果表明,天然海泡石经改性后对Cr6+有很强的去除能力。在pH值3～6、Cr6+0～35mg/L条件下,按1L废水加入2.5g改性海泡石进行静态吸附12h,Cr6+的去除率达到99.5%。该方法工艺简单、成本低,且不带来二次污染。更多还原

【Abstract】 The Cr6+\|containing wastewater treatment of electroplating works by meerschaum was discussed. Results showed that the nature meerschaum after modified had strong absorption effect to Cr6+. Adding 2.5 g modified meerschaum in every 1 L wastewater containing Cr6+ from 0 to 35 mg/L, the removing rate of Cr6+ was above 99.5% after adsorbed statically under pH from 3 to 6. This method was simple and low cost without secondary pollution.更多还原
