abstract={One of the threats of environmental damage now is wastewater pollution.
Electroplating wastes can pollute the environment and health corrupt the even end
in death as they contain heavy metal elements. Eggshell is a waste in everyday
life are used as materials processing waste to replace chemicals that help with the
clean industry. In this study in trying an adsorption method using eggshell waste
as an adsorbent to adsorb electroplating wastewater containing heavy metals As
with the adsorbate. With eggshell adsorption process as adsorbent divided into
several sizes (mesh) ie 10, 30, 60 and 100 mesh with contact time variation 30,
60, 90, 120 minutes as the independent variable in the research and stirring speed
as fixed variables. The liquid waste is used electroplating wastewater containing
heavy metal Pb of 35.80 mg / l. The system used in this study is the adsorption
studies using a batch system.
After analysis using AAS can be said in 90 minutes with a 100 mesh size
eggshells most well reduce levels of Pb in electroplating waste is equal to
98.90%. If within a short amount of adsorbent not be mixed evenly and if a long
time adsoben will be at maximum. Research using the eggshell is successful in
reducing Pb in electroplating wastewater is able to reduce Pb content of 98%.
