Study on the removal of non-ion surfactants from wastewater by modified fly ash
Online published: 2010-10-01
The ability of fly ash to remove non-ion surfactants OP 10 from wastewater has been investigated.The results show that fly ash modified by the modification reagent of n(HCl) ∶ n(H2SO4) = 1 ∶ 1 is effective to adsorb environmental harmful substance OP 10 in wastewater. When the concentration of OP 10 is 300 ~ 1 800 mg/L in the wastewater, the amount of modified fly ash used is 200 g/L and the particle size is 74 ~ 83 μm, under pH 1~3 experimental condition, the efficiency of OP 10 removal rate is above 92%.
Key words: wastewater containing non-ion surfactants; adsorption; fly ash
