Activated carbon solvent recovery technology

Activated carbon solvent recovery technology

My country has successfully applied activated carbon solvent recovery technology in printing, paint, rubber, fire explosives, film, asbestos products, papermaking and synthetic fiber industries, and generally adopts activated carbon intermittent fixed bed recovery technology, which has achieved significant social and environmental benefits.

Activated carbon adsorption treatment of high COD dyeing wastewater

Activated carbon adsorption treatment of high COD dyeing wastewater

There are many kinds of dyes commonly used in the modern textile printing and dyeing industry.There are different types of dyes, such as acid dyes, reactive dyes and disperse dyes, which are used for dyeing animal, plant and man-made fibers.The chemical properties of dyes vary greatly, and some dyes and their derivatives are very harmful to the environment.The water-saving strategies widely used in the dyeing process often cause the plant's biological wastewater treatment plant to fail due to overload of chemical oxygen demand (COD).In order to deal with this problem, a renewable adsorption-oxidation process has been studied to deal with COD, mainly using highly nanoporous activated carbon as a COD adsorbent.

Application of activated carbon in the adsorption of bisphenol S

Application of activated carbon in the adsorption of bisphenol S

Bisphenol S (BPS) is a major environmental endocrine disruptor that can cause abnormal functions of the biological endocrine system.In addition, BPS is often found in surface water, urban sewage, sediments, and daily necessities.The continued accumulation of BPS may increase potential risks to the ecological balance.In order to remove bisphenol S from the aqueous solution, we use a simple and effective adsorption method. Activated carbon is used as an adsorbent in different fields due to its well-developed internal porous structure, relatively high surface area, large adsorption capacity and a variety of functional groups. Activated carbon is used as the adsorbent this time.

The main factors affecting the liquid phase adsorption of activated carbon

The main factors affecting the liquid phase adsorption of activated carbon

Since activated carbon is a porous adsorbent with a non-polar surface, and although water molecules are associative, they are polar solvents, therefore, activated carbon adsorbs organic matter from an aqueous solution is an ideal state.
