Nutshell gold looks black granular activated carbon. Porosity developed, large surface area ratio, strong adsorption performance, small bed resistance, chemical stability having dual characteristics of physical adsorption and chemisorption, is a very good adsorbent. Fruit The main gold shell activated carbon adsorption performance, it is concerned with the pore structure of activated carbon. The specific surface area and pore volume ratio are big, so, to a large extent determines the microporous activated carbon adsorption capacity in solid charcoal surface adsorption occurs mainly in two ways, namely physical adsorption and chemisorption chemisorption is monolayer adsorption, waste water and exhaust gas can be removed in the polar contaminants and some metal ions; physical adsorption of molecules capable of forming a multi-layer adsorption can effectively absorb waste water and emissions of organic pollutants. applies to domestic water, industrial water and wastewater deep purification, dechlorination, bleaching, deodorizing and gold refining and other aspects.
