Granular Activated Carbon (GAC) is a specific preparation of activated carbon, or activated charcoal. It has been used as a purification agent since the early 19th century. Today, activated carbon in various forms, including granular, is used in a wide range of industrial, commercial, and home applications to remove contaminants.
Preparation of activated carbon method is based on the application and the AC quality is based on the iodine number. normally Ac produced from Coconut shell in my concern the chemical method is ...
using activated carbon is its costeffectiveness. Researchers in the recent past have mainly focused on the preparation of the activated from agricultural waste materials as an alternative for the commercial activated carbon. Consequently, numerous low cost alternatives have been proposed including sago
The prepared activated carbon has welldeveloped microstructure and high microporosity. According to the data obtained, Chinese fir sawdust is a suitable precursor for activated carbon preparation. The obtained activated carbon could be used as a lowcost adsorbent with favorable surface properties.

R. China. (2) Department of Chemical Engineering, Xiamen ... activated carbon samples were dried for 12 h at 120 oC.
The demand for activated carbon is increasing owing to the increased utility of the carbon materials in pollution control. As a result, cost of activated carbon is also growing depending on the application. Designing ways for the production of activated carbon through economic ways is the need of the hour. A range of low cost, easily
Oct 19, 2019· Activated charcoal, sometimes called activated carbon, is useful for purifying contaminated water or polluted air. In emergency situations, activated charcoal can be used to remove dangerous toxins and poisons from your body. Before you can activate the charcoal, you''ll first need make homemade charcoal by burning wood or fibrous plant material.
Activated carbon preparation. Iran is the third largest producer of walnuts in the world, with 10% of global output [].In this study, walnut shell was used as the carbonaceous source material for preparation of the activated carbon.
Carbonization of carbon obtained from plantain (Musa paradisiaca) stem was achieved at a temperature of 400°C for one hour. The carbonized carbon was divided into two parts to be activated separately. The activated carbon CPPAC (carbonized plantain phosphoric acid activated carbon) and CPZAC (carbonized plantain zinc chloride activated carbon) were produced via the chemical activation .
Activated carbons were prepared from lignin by chemical activation with ZnCl 2, H 3 PO 4 and some alkali metal compounds. The influence of carbonization and activating reagent on the pore structure of the activated carbon was investigated.
However, the sale price of activated carbon is high. The price of activated carbon ranges from to 1 per pound, which equals 1320 to 2200 per ton. The main applications of activated carbon are air pollutant control, water/wastewater treatment, control of Volatile Organic Carbons (VOC), Hg capture, and color/odor removal for example.
