REMOVAL OF CADMIUM FROM SURFACE WATER OBTAINED AT THE OIL EXPLORATION SITE OF NIGER-DELTA REGION, NIGERIA: OPTIMIZATION OF THE BATCH-SORPTION PROCESS
Publication Date : 09/10/2022
The aim of the study was to quantify cadmium contaminant level in surface water situated near oil exploration activities in the Niger-Delta Region and to optimize the conditions, i.e parametric factors for batch-sorption process of cadmium removal by studying as a function of the contact time, temperature, dosage (sorbent loading) and agitation speed using already synthesized bimetallic supported carbon nanotube sorbents. The batch-sorption process was fully optimized in a system using 2^4 factorial model. The optimum values of process factors were found to be contact time, 59.729 min, temperature 30.989 oC, dosage 0.112 g and agitation 594.988 rpm. The removal efficiency which is the maximum value, i.e 99.071 % shown by the model and 98.96 % experimentally verified, having desirability of 1.000 thus, showed the validity of the model.
