Ībdelnaeim MY, El Sherif IY, Attia AA et al (2016) Impact of chemical activation on the adsorption performance of common reed towards Cu (II) and Cd (II). Also, the comparison of the physical mixing method and the impregnation method in activation with alkali metals indicates that the activated carbon obtained through physical mixing had a higher porosity than the activated carbon produced by the impregnation method.Ībbas AF, Ahmed MJ (2016) Mesoporous activated carbon from date stones ( Phoenix dactylifera L.) by one-step microwave assisted K 2CO 3 pyrolysis. Activating with potassium hydroxide in terms of surface area and efficiency shows better results than sodium hydroxide for various applications. Potassium carbonate, in comparison with potassium hydroxide, produces higher yields and a higher surface area for the adsorption of large pollutant molecules such as dyes. Zinc chloride generates more surface area than phosphoric acid but is used less due to environmental concerns.

Activation with phosphoric acid is commonly used for lignocellulosic material and at lower temperatures. Eighteen articles report the activation with potassium hydroxide, 17 with phosphoric acid, 15 with zinc chloride, 11 with potassium carbonate, nine with sodium hydroxide, and 11 with new activating agents. We selected 81 articles from Google Scholar, PubMed, Scopus, Science Direct, Embase and Medlin databases. We compare the impregnation method with the physical mixing method used in activating with alkali hydroxides. Here, we review chemical activators used to produce activated carbon.

Selection of the chemical activator agent is a major step controlling the performance and applicability of activated carbon. Activated carbon has many applications in the environment and industry for the removal, retrieval, separation and modification of various compounds in liquid and gas phases. Alexander! You are the best doctor that I have ever had the good fortune to have treat me.Activated carbon refers to a wide range of carbonised materials of high degree of porosity and high surface area. Greg Alexander's care and treatment when I did.

Greg Alexander and what would have happened if I had not received Dr. I still get emotional when I think of how much benefit I received from Dr. Alexander has improved my quality of life, my outlook and my attitude.

When I workout now, I am not in pain the next day like I had been before I received Dr. I am stronger physically than I have been in many, many years. I have started running at the park again. I can turn around and look out the back window when I put the car in reverse again. The range of motion in my back has improved. Now, I can sleep more deeply and have dreams again, which I have not had in many years. Alexander kept his promise, and I feel like I have my young body back. Alexander used the painless Activator Method.

Alexander did not use his hands to make adjustments to my spine. Alexander promised he could help me and give me my young body back. Alexander determined the cause of my problems and then treated the cause of the problems rather than just treating the symptoms. Alexander took my x-ray and did some thermal scans of my back and showed me in the x-rays where my spine was out of alignment and how only half of the joints in my spine were moving because of a car wreck from 20 years ago and how a pinched nerve in my neck was causing the thumb problem. I was only 50 years old and did not think my body should be breaking down so much. My M.D., a general practitioner, had prescribed Celebrex, an NSAID, saying "it is rough to get older", just treating the symptoms without looking for the cause, presuming it was merely aging. I had been having chronic back and neck pain for 20 years. My thumb had stopped working and was very painful.
