The Adsorption Characteristics of Phytochemical on Supporters

Abstract:

The objective of this research is to study equilibrium adsorption, adsorption isotherm and the amount of the phytochemical called Micronice Bio MEX 3, which is adsorbed on various supporters. Micronice is a biodegradable chemical liquid product collected from Technogreen Company Limited. The supporters in this work are activated carbon, zeolite and brick which are used as adsorbents. The supporters were immersed in the Micronice with various periods to find out their adsorption equilibrium time. The results show that the adsorption equilibrium time for all supporters is 60 minutes and the mass adsorption percentages of activated carbon, zeolite and brick are 14.05%, 1.58% and 2.24%, respectively. An adsorption isotherm can be described by the Langmuir and Freundlich models. The Freundlich constants of activated carbon, zeolite and brick are K_F = 4.76 x10^-8 (mg/g)(L/mg)^1/n , 7.15x10^-8 (mg/g)(L/mg)^1/n and 1.10x10^-4 (mg/g)(L/mg)^1/n , n = 0.772, 0.619 and 0.922, respectively. The Langmuir constants of activated carbon, zeolite and brick are K_L = 756.62 L/mg, 12,924 L/mg and 3,918.60 L/mg, q_o = 1,428.57 mg/g, 44.25 mg/g and 303.030 mg/g. The results present that the adsorption mechanism of all supporters can be well described by both Langmuir and Freundilch models and the best supporter is activated carbon.
