如何利用花生壳制活性炭(实验室制法)（How to make use of peanut shell to make activated carbon (Laboratory method)） How to make use of peanut shell activated carbon (Laboratory method).Txt beg, but not, but not at all, this is the biggest sorrow. Pay the heart to get the heart, but may also hurt thoroughly. Distance can protect itself, but it is destined to be lonely forever. Activated carbon should be activated at first. The surface of activated carbon tends to adhere to many oil and clog pores, affecting adsorption capacity. If treated with a zinc chloride solution, the oil deposited on the surface of the carbon can be removed, thereby increasing the pores of the carbon and enhancing the adsorption capacity. This process is called activation. The preparation of activated carbon can generally be done by the following process: The sawdust (or peanut shell, walnut shell) into the soaking solution of zinc chloride in a few hours, full absorption of zinc chloride was removed after drying, into the iron pot, the lid (iron cover to open a hole, stop heating and heating) were carbonized to no longer produce gas, and then the carbon the chip was rinsed to remove zinc chloride and other impurities, and then drying and grinding. ======================================================== The following is from the determination of activated carbon prepared from peanut shells and their properties Henan chemical industry, 2006:23 (11) -19-20 Authors: Kong Haiping, Jin Huijie, Luo Tingliang Abstract: zinc chloride, activated carbon with peanut shell as raw material for the preparation of high performance, and analyze the influence of experimental conditions. The optimum preparation conditions through orthogonal experiment: peanut shell and zinc chloride solution liquid material ratio of 1: 2.5, zinc chloride solution concentration 60%, activation temperature of 600 C, the performance of the activation time of 90 min. and the condition of activated carbon were determined, and the apparent density of 0
