Metal Extraction and Analysis on The Effect of Alkyl Chain Length on Thiosalicylate Based Ionic Liquids

The process of removing metal is one of the important parts in industial wastewater
treatment. Many technologies have been developed to do so, such as dissolving an
organic solvent (kerosene, toluene, etc.), or using extraction agent However, none of
them is regarded as green technology because they cause detrimental effect to the
environment and human body. The use of Ionic Liquids (!Ls) is believed to be the
answer to overcome the problem.
Ionic Liquids are generally defined as molten salts that are consisting entirely of
anions and organic cations. This project is designed as further study for
Thiosalicylate anion-based ILs on metal extraction process, and efficiency of
inco1porating different type of chain length. There are 3 (three) types of alkyl chain
length tested, hexyl-, octyl-, and dodecyl- chloride. Simulated industrial wastewater
is used for the experiment by inducing heavy metal (Cil+, Ni2
+, etc.) into the
deionized water. At last, the whole project is expected to proof that metal extraction
by using Ionic Liquids is promising, as well as to find the most optimum
Thiosalicylate anion-based !Ls to be utilized by considering several parameters.
