Study of Heavy Metal ion adsorption from Synthetic Wastewater with the help of biomass and analysis of Mathematical Model
Abstract: The biofilm matrix is a mixture of secreted polymers, metabolites and nutrients ingested, lysis solution products, and even particle debris. This matrix, which is polyanionic by nature, is essential for the activated carbon of metal cations. In this study, the heavy metal adsorption mechanism in biofilms is modelled in one spatial dimension. The numerical method is a free-boundary value issue for nonlinear parabolic and quadratic partial differential equations. Parabolic equations …
