【摘要】 研究了海藻粉对废电解液中Cu2+的吸附行为,实验结果表明:在海藻粉的投加量1.5 g,摇床转速120 r/min,温度25℃,吸附时间60 min,最佳pH值4～7条件下,对Cu2+浓度为80 mg/L的模拟废电解液进行吸附,最大吸附率为97.8%,共存离子不会影响对Cu2+的吸附率。实际废水的处理结果表明,对废电解液中Cu2+吸附率达到99.5%,其它金属离子经过吸附后也可达标排放。更多还原

【Abstract】 The adsorption process of Cu2+ in waste electrolyte with algae powder is studied.The experimental results show that the best adding ammount of algae powder is 1.5 g;the table concentration speed is 120 r/min,the temperature is 25 ℃,the adsorption time is 60 min.At the best pH value range of 4~7,the adsorption of simulation waste electrolyte of =80 mg/L is carried out,which show that the maximum adsorption rate is 97.8%,and coexisting ions cannot affect the Cu2+ adsorption rate.The actual waste water processing results indicate that the adsorption rate of Cu2+ in waste electrolyte can be up to 99.5%,other metal ions may also reach the sign discharge after adsorption.更多还原
