| Abstract_FL | Taking scoria as an adsorbent material,we studied its adsorption effect on SO2-4 in low temperature water and its influence factors.The experimental results show that the scoria has a good adsorption effect on SO2-4.When the initial mass concentration of SO2-4 is 100—1 000 mg/L,the adsorption amount increases with the increase of the initial mass concentration.Whenρ(SO2-4 )=1 000 mg/L,the maximum adsorption amount is 6.42 mg/g,and the shortest equilibrium time is 4 h.The optimum pH for adsorption of SO2-4 is 7.Ca2+and Mg2+have a slight promoting effect on SO2-4 adsorption by scoria,while Cl- and NO-3have inhibitory effect. |
