The mineral-based sorbents Filtra P, Polonite, natural wollastonite and water-cooled blast furnace slag (WCBFS) were studied in terms of their PO(4) removal performance. Results from a long-term column experiment showed that both Filtra P and Polonite removed >95% of PO(4) from the applied synthetic solution, and that the used filter materials had accumulated several (1.9-19) g kg(-1)P. Phospho...

Many natural products have demonstrated functionality as novel, green sorbents for organic compounds.

Oil and gas production has an adverse impact on the ecological state of Russian Arctic. The local natural materials, such as peat, moss, reindeer moss are considered naturel sorbents in wastewater treatment technologies. sorption properties these materials were studied. isotherms at different initial concentrations pollutant (250, 50, 0.5 mg/L) constructed. patterns changes intensity oil produc...

The injection of sorbents upstream of a particulate control device is one of the most promising methods for controlling mercury emissions from coal-fired utility boilers with electrostatic precipitators and fabric filters. Studies carried out at the bench-, pilot-, and fullscale have shown that a wide variety of factors may influence the mercury removal effectiveness. These factors include merc...
