    Preparation of activated carbon from natural plant waste
    (October University for Modern Sciences and Arts, 2020) Abdel Aziz, Omar Hassan Ibrahim
    Background: Waste elimination is the most important hazard that threatens human and animal health; these problems are growing every passing day. On this purpose, human beings have used the methods of waste treatment in order to help nature which is still artificial. Most of the waste treatment methods and systems used are very effective. Thus the scientists are working to develop new environment-friendly and low cost treatment systems to contribute in both environment and economy via the use of the wastes products and surplus resulting from the human activities (industry, agriculture, domestic, etc.). The abundant availability of agricultural wastes makes them good sources of raw precursors for preparation of low good activated carbons in the points of my view pomegranate processing industry would serve as a potential alternative precursor for the preparation of low activated carbons. Recently many scientists worldwide turned their interest to the preparation of adsorbent materials which were used for many applications of industrial wastewater treatment. Objective: the present study reveals that the preparation of activated carbon from pomegranate peel has been used as a low cost and eco-friendly bio adsorbent material. In view of these facts. The prepared activated carbon applied to removal of toxic organic pollutants of dyes from water. Methods: The activated carbon produced from pomegranate peel waste by chemical activation process with two type activating agents like zinc chloride, and phosphoric acid. A systematic investigation of the effect of impregnation ratio, activation temperature and activation time on the properties of the activated carbon for each activating agent was done. The optimum preparation conditions together with the effected of these conditions on the yield and efficiency of produced AC have been studied .The chemically activated carbons were characterized by measuring iodine and carbon yield percentage. To decide the superiority of a precursor over the other characterization of the precursor was done using various methods like: CHNS elemental analyzer, Proximate analysis and as well as the performance and absorbing capacity of the activated carbons produced in removing different dyes as organic pollutants in synthetic wastewaters. Results: Based on the results obtained, it appears that the properties of (PP) has rich in elemental carbon content (45-55%), low ash content (2.5%) , moisture (7.1%) and high volatile matter 10 (75%) all this data are a pointer that it will give a high quality activated carbon. activated carbon has been prepared by the chemical activation process two types of chemical activating agent (Zncl2) and (H3Po4) high BET surface areas1350 m2/g, total pore volumes 0.66 cm3/g, iodine number and 714 mg I2/g C high carbon yield 39.4 % by using H3PO4 than zncl2 at Final activation temperature = 600 °C, Activation time = 1 h and Impregnation to PP Ratio (5: 1 wt%) as compared.
