Experimental study on activated carbon adsorbinghydroquinone

Under static condition,hydroquinone-containing wastewater was treated by activated carbon,the adsorption effects of activated carbon forhydroquinone-containing wastewater under different conditions were compared,meanwhile,the influences of pH value,activated carbon dosage,oscillation time,temperature,concentration ofhydroquinone,oscillation velocity and electrolyte of the wastewater on adsorption effect were determined.The results of the test showed that: under the condition that,the dosage of activated carbon was 35g/L,the pH value was 6.5,the oscillation time was 3.5h,the temperature was about 35 ℃,the best treatment effect ofhydroquinone-containing wastewater whose mass concentration was 100mg/L was obtained,the removal rate reached 99%.
