Removal of chloride ions in waste water using activated carbon from maize cobs and coconut shells

Abstract

In a study carried out to remove chloride ions from a waste water sample using activated carbon from maize cobs and coconut shells. A waste water sample from surface run off water was collected. The initial chloride content of ions in waste water was determined as (10196.07317mg/L Cl). This is a highly unacceptable level of chloride ions in water therefore there is need to remove the chloride ions in this waste water sample. Activated carbon was used as the adsorbent to remove the chloride ions in water. The activated carbon was made from coconut shells and maize cobs. It was then characterized. An orbital shaker was used to determine the time contact for 8 intervals from 0-70 minutes. The results were tabulated. The percentage removal from the beakers with activated carbon from coconut shells was the highest with (77.18906532%) and the one from maize cobs was (70.5539021%). This indicated that coconut shells are a better source of activated carbon than maize cobs.
