Removal of chromium ions (VI)‎ from aqueous solution by utilizing dried tea waste and pomegranate peel as mixed adsorbents

Abstract EN

The present study was performed to evaluate the removal of chromium ions (VI) from aqueous solutions using dried tea waste and pomegranate peel as mixed adsorbent.

Batch experiments were performed under various process parameters like pH, contact time, biomass dose, and initial chromium (VI) concentration to investigate the optimum conditions for removal percent and the maximam removal capacity of chromium ions (VI).

High removal percent was achieved at optimum parameters determined as follows: pH= 1.4, contact time= 120min, shaking rate= 250 rpm, solid particles= 180µm, and chromium concentration= 20ppm.

Around 88.1% of chromium ions (VI) was removed from aqueous solution with maximum removal capacity of qm = 13.03 mg/g at these conditions.
