| The influences of various factors on the absorption ability of Na2CO3 modified tailings,CTMAB(cetyltrimethylammonium bromide) modified tailings and unmodified tailings to adsorb Pb2+ in the simulated wastewater are studied systemically.The results indicate that when the sorbent dosage is 7.5g/L in the simulated wastewater,the time is 4h,the initial Pb2+ concentration in the simulated wastewater is 200mg/L,the initial pH of the simulated wastewater is natural,the adsorption effect is best.Further more,the ad... |
