Abstract: In general, the present disclosure is directed to a soyhull-based activated carbon. The soyhull-based activated carbon comprises a Brunauer-Emmett-Teller (BET) surface area of from about 750 m2/g to about 2900 m2/g and a micropore volume of from about 0.50 cm3/g to about 1.2 cm3/g.

Abstract: The invention is directed to methods for improving the DOM uptake of granular activated carbons and the carbons formed according to the methods. The methods include treating starting materials so as to provide a combination of physical and chemical characteristics favorable for DOM uptake. Particular methods utilized depend upon the characteristics of the starting materials but generally include at least one of: increase in surface area of the materials found in pores greater than 1 nm; increase in overall basicity of the materials; and impregnation of the materials with an iron species. The processed materials exhibit improved uptake of DOM from natural waters as compared to previously known GAC materials.
