Ph of activated carbon
WebThe ash is mainly composed of silica and aluminium and the amount depends on the base raw material used to produce the product. Typical values are 2-3%W/W for coconut shell based activated carbon, 5%W/W for wood based activated carbon, and 8-15W/W% for coal based activated carbons. Quality indicator for the spent carbon WebThe adsorption process depends upon 5 key factors: 1) physical properties of the activated carbon (surface area and pore size distribution); 2) the chemical makeup of the carbon source (amount of hydrogen and oxygen); 3) the chemical makeup and concentration of the contaminant; 4) water pH and temperature; and 5) the length of time the water is ...
