1. Introduction. Increasing concerns about harmful pollutants in the environment have pushed for a need to develop an efficient adsorbent or a highly sensitive chemical sensor for toxic materials, .Porous materials, such as activated carbons, mesoporous silica or carbons,, zeolite,, and metal organic frameworks (MOF), have been utilized as adsorbents or sensing transducers.

Activated carbon (also called activated charcoal, activated coal or active carbon) is a very useful adsorbent. Due to their high surface area, pore structure (micro, meso and macro), and high degree of surface reactivity, activated carbon can be used to purify, dechlorinate, deodorize and decolorize both liquid and vapor applications.

Activated carbon is the most common adsorbent in adsorption operation of water treatment, and many other adsorbents including activated zeolite, activated aluminum oxide, silica gel, various synthesized adsorbents, and different modified natural materials, such as chitosan, are often used in water treatment.

Activated carbon is the most widely used adsorbent because of its low cost, exceptionally high porosity, tuneable pore size and high adsorptive capacities [15, 16]. The raw materials widely used initially for the production of commercial activated carbon are coal, bone char, peat, petroleum coke, lignite, wood and other biomass sources.

"activated carbon," is the adsorbent most commonly used to attract and hold dissolved contaminants . Activated carbon is made from carbon-based materials like coal or wood that is first heated without oxygen to produce charcoal and tar or pitch, which bubbles out. The charred material is then heated with steam or carbon dioxide to above

laden activated carbon is achieved by exposing it to heat, e.g. in water vapour, hot gas or vacuum. The resultingrecovery of adsorbates plays an important role in solvent recovery processes, for example: If an adsorbent such as activated carbon is brought into contact with an aqueous solution or a gaseous medium containing adsorbates,
