Removal of Chloride Ion from Industrial Effluent Using Mango Bark Activated Carbon

Abstract

This study assessed the possibilities of using
inexpensive adsorbents to remediate
industrial wastewater. Agricultural waste
such as mango bark activated carbon has
been used to eliminate impurities from
wastewater for the treatment of industrial
effluent from the paint production industry.
Water analysis was carried out to determine
the physicochemical parameters of the
wastewater before and after treatment.
Results showed that low-cost adsorbents such
as mango bark can be utilized for absorption
of contaminants from industrial wastewater
from the paint production industry with a
concentration range of 5 to 20mg/l. Also,
results revealed the efficient use of mango
bark-activated carbon in the reduction of
chloride ions. The effect of the amount of
adsorbent on the removal of chloride ions by
mango bark was determined and it was found
that results obtained for each of the
parameters ranged accordingly from (3.86-
2.51mg/l). The efficiency of mango bark
activated carbon was also determined and the
result according to the list of wastewater
properties and their doses was (49.93-
67.44%). Maximum monolayer adsorption
capacity was determined by adsorption
isotherms such as the Langmuir and
Freundlich isotherms. When compared, the
result showed that adsorption data best fit the
Freundlich Isotherm because the slope gave a
positive value of (2.4364) whereas the
Langmuir Isotherm gave a negative slope
value of (-0.002).
