Mathematical Model and Experimental Study To Optimize Rates Constants of Desorption And Adsorption of The Waste Water Using Palm Fronds
Physical, mechanical and multi â€“ step chemical treatments on the adsorptivity of palm fronds adsorbent for the removal of 5 waste metal components from wastewater was studied and estimated in this paper. Three techniques are used for palm frond to produce modified activated carbon as adsorbents. Physical treatment is represented in the furnace at 600 oC. Mechanical treatment is established more suitable surface area from 300Âµm2 to 500 Âµm2 to increase efficiency of adsorbent.Â Chemical treatment of palm fronds used Acetone â€“ ethanol - methanol treated palm fronds. The fixed bed column study was achieved under multi layered fixed bed columns. It was discovered that, the adsorption of 5 metals were expressively increased in the following order: Acetone â€“ ethanol â€“ Methanol treated palm fronds. The highest percentage reduction of the area under the curve was represented by chemical treatment for palm fronds reached 98.74%. Derived mathematical model to describe the system and compared it with experimental results in active accuracy. Proposed model includes the most significant variables like partial pressure and concentration of waste metal acts on rates of adsorption and desorption. Newton Raphson is a mathematical optimization technique used to determine the optimal values of rate constants adsorption and desorption of the waste of palm fronds for Cu, Cd, Zn, Ni and K to increase the ability of mathematical model. The freshness of this study is used to assess the carrying into action of bio waste to get rid of waste metals due to utilize more than one technique to compute the rate constants of adsorption and desorption. However, further studies are asked to emphasize with the results of this survey using this active technique.
