Efficient phenol removal from petrochemical wastewater using biochar-La/ultrasonic/persulphate system: characteristics, reusability, and kinetic study.

abstract：:The eutrophication of many rivers and lakes is attributed to the anoxia and the increasing internal loading of nutrients from sediment. A novel sustained-release composite (SRC) synthesis of stearic acid and calcium peroxide (CaO2) was applied to supply a water body with oxygen endured in this study. The influences of...
