Modeling And Simulation Of Absorption Rate Of Zinc From Polluted Soil By Bushgreen Roots
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 8
Abstract
The rate of absorption of Zinc by Bushgreen roots was studied. Empirical model was used to model the concentration of Zinc absorbed by Bushgreen roots with time. It was observed that the empirical equation relating the concentration of Zinc in Bushgreen roots with time is a polynomial of second degree with a correlation ratio of R2= 0.977. The rate of absorption follows second order rate equation. The mass transport coefficient (k) was determined to be 1.30779 x 10-4 ug/g-day. The model was validated and the experimental values of concentration of Zinc in Bushgreen roots agree between 92.41 to 99.29 percent with the value predicted by the model developed. The model was also simulated to predict absorbed concentration of Zinc at early stage of root development when the concentration was difficult to measure experimentally. It was observed that the trend of the values predicted was similar to that of the experimental measured values.
