the use of activated carbon which is used as an adsorbent. This is due to the adsorptive properties of activated carbon(Cecen & Aktas‚ 2011). Agricultural by-products represent a considerable quantity of harvested commodity crops. The use of by-products as precursors for the production of widely used adsorbents‚ such as activated carbons‚ may impart a value-added component of the overall biomass harvested. In most developing countries‚ the activated carbon is

removal of toxic or recalcitrant organic pollutants from wastewater. The most common adsorbents on the market today are activated carbon‚ silica gel‚ and alumina‚ because they have large surface areas per unit weight. Activated carbon is produced by roasting organic material to decompose it to granules of carbon - coconut shell‚ wood‚ and bone are common sources. Also activated carbon is the most commonly used adsorbent in wastewater treatment. As Silica gel is a matrix of hydrated silicon dioxide

medicinal properties of charcoal are given strong boost by the United States (a book that tells how to prepare and use medicines). Besides giving direction for making charcoal‚ the Dispensatory lists several problems that can be treated with charcoal. Activated charcoal exerts its effects by absorbing a wide variety of drugs and chemicals. The important work of charcoal powder in the treatment of diseases is to adsorb chemical substances that are harmful to the body‚ like germs‚ viruses‚ toxins‚ wound secretions

(75% of that is salt water‚ only leaving a 25% as fresh water which can be used for consumption. 70% of the fresh water of our planet is still frozen in the icecaps of Antarctica and Greenland; while the remaining percentage is present as soil moisture‚ or it lies underground as groundwater. Main Problem How can the seawater be utilized for the consumption of different organisms? Sub problems How will the results of the said
