Adsorption Isotherms And Kinetic Studies On The Removal Of Lead (II) Ions By Rubber Seed Coat

Rubber seed coats (RSC) were treated with acid and base to investigate the removal of lead (II) ions by adsorption process. Among all biosorbents that were investigated, base treated rubber seed coats showed the highest removal percentage of lead (II) ions. The experimental data were fitted to Langm...
