SOLID SUPPORT ON THIOSALICYLATE BASED IONIC LIQUID FOR METAL EXTRACTION

Providing safe drinking water for human being has always been the subject of interests for many
scientists. Since decades ago, serious efforts have been taken to solve the drinking water
pollution issue especially those cases that involved the lethal effects on human. Cleaning water
from heavy metal such as nickel, cadmium, lead and iron is always be very challenging since
some conventional methods used such as solvent extraction method has harmful effects on
environment. In this research the choice of having metal extraction using greener technology will
be applied by using ionic liquid as the extraction agent. Octylpyridinium thiosalicylate ionic
liquid are stable at high temperature will be the modified by syntheses process with silica as the
absorbent material. The syntheses of ionic liquid will involve the process of quarternization,
purification, drying and metathesis. The parameters that will be varied in order to get high
efficiency of metal removal is the variation of silica loading. Analysis on the efficiency of this
method will be evaluated through the results obtained from Atomic Absorption Spectrometer
(AAS) reading.
