dc.description.abstract |
Maredan clay is a type of clay composed of tetrahedral silica and octahedral
alumina compounds which can act as adsorbents. This research aims to determine
the optimum conditions of solution pH (variations 2, 4, 6, 8, 10, and 11) on the
adsorption efficiency of Maredan clay in adsorbing lead(II) ions. Maredan clay
was characterized by determining functional groups using testsFourrier Transform
Infra-Red (FTIR). The results of Maredan clay analysis using FTIR show that
before and after adsorption there are Si-OH, Si-O-Si, Si-O-Mg, Si-O-Al and –OH
functional groups, while after adsorption there are additional Pb-O-Pb functional
groups. Optimum adsorption parameters were obtained at pH 10 with an
adsorption efficiency of 98.57% and an adsorption capacity of 7.8048 mg/g. |
