Biosorption of Copper (II) from Simulated Wastewater Using Spent Coffee Grounds: A Column Study
Aileen D. Nieva, Reuben James Q. Buenafe, Drex R. Guinto, and Jean Claudine F. Leaño
Abstract—Biosorption of contaminant like copper using
agricultural wastes like spent coffee grounds requires testing the
compatibility of the sorbents with the sorbates and finding the
optimum conditions for the process. This study is needed to
avoid the disruptive effects of biosorption such as the generation
of more wastes that eventually disrupts the balance in the
environment. This paper is a baseline study to optimize the
performance of adsorption of copper in wastewater using two
species of spent coffee grounds i.e., Arabica and Robusta. The
adsorptive capacities of pure blends of both species were
compared to the 50:50 blend in a fixed-bed column. It is aimed to
determine the optimum bed height, coffee variety and flow rate
inside the column to reduce waste generated through
experiments. It was found out that the optimum conditions were
7 cm bed height and 20 mL/min flow rate. The adsorptive
capacities of the three varieties were 10.47, 13, and 15.41 mg/g
for pure Arabica, 50:50 blend and pure Robusta, respectively.
