The effects of reaction time, oxidant concn., oxygen-coal ratio and microwave power on FA yield are detd. ,Sulfuric acid,-acetone was applied to purify the primary FA products. The results indicate that the oxidant concn. is a sensitive factor affecting the yield of FA, while reaction time has little effect.

1/12/2014, · While acidification with ,sulfuric acid, is the universal means of coagulant resolubilization, there is a lack of consensus on the optimum operational pH. More metal coagulant can be solubilized at lower pH values but this effect has been reported to diminish below pH values of 1, at concentrations of approximately 2,500 mg/L Al (Saunders and Roeder, 1991 ).
