The compound 4-chlorophenol (4-CP) is known to be a highly toxic having harmful effects on human health and the environment. To date, removal of 4-CP by advanced oxidation processes (AOPs) has attracted tremendous attentions. persulfate-based AOPs show higher oxidation, better selectivity, wider pH range, no secondary pollution compared traditional Fenton-based AOPs. Carbon materials with low c...

Catalytic persulfate technology is a new type of catalytic that has been extensively studied in recent years. Among them, the copper and silver materials synthesized by microwave assist have broad application prospects are class catalysts with excellent performance, environmental friendliness, stable structure. This article introduces material loaded metal activated carbon, analyzes mechanism o...

1,4-dioxane is an emerging contaminant that was used as a corrosion inhibitor with chlorinated solvents. Metal-activated persulfate can degrade dioxane but reaction kinetics have typically been characterized by a rapid decrease during the first 30 min followed by either a slower decrease or no further change (i.e., plateau). Our objective was to identify the factors responsible for this plateau...

Zero-valent iron [Fe(0)]-biochar composites, namely, Fe(0)-included biochar and biochar-coated Fe(0), were synthesized their catalytic performance in the activation of persulfate for phenol degradation water was evaluated. In presence Fe(0)-biochar biochar-persulfate Fe(0)-persulfate systems showed higher removal than a system by 11.6% 20.7%, respectively. The difference between Fe(0) because h...

Advanced treatment of biologically processed palm oil mill effluent (BIOTPOME), which possesses a potential danger to the water sources is required meet Malaysian discharge standard, as BIOTPOME contains high level chemical oxygen demand (COD), suspended solids and grease even after going through conventional process. The significant but insufficient efficiency ponding system in Malaysia urged ...
