text: When no reducing material is present, the concentration of organic materials in the wet process phosphoric acid is 1,100 mg/l as calculated on the basis of the carbon, which indicates that the adsorptive capacity of the active carbon is almost zero, and it is thereby impossible to reduce to concentration of organic materials to a level lower than this concentration.
