Study for the production of local adsorbent from tea and coffee wastes for removal of lead ions from an aqueous solution

Abstract

In this article, the manufacture of low-cost adsorbents from tea and coffee waste for the removal of lead from an aqueous solution was batch experimental of the created adsorbent. After charring tea and coffee waste, there was a considerable improvement in surface area and other physical parameters such as density, bulk density, and porosity. In the batch studies, different dosages of both adsorbents were utilized, and the equilibrium isotherm was of the very favorable type for adsorbents, and two models (Freundlich and Langmuir) were used, and the data corresponded well with the Freundlich isotherm. a random set of experiments showed a removal degree efficiency of lead reaching (99 percent ).production
