Abstract

The Study about, kaoline adsorbent modified with a surfactant (organokaoline) to absorb metal ions Mn (II) in aqueous solution. Modifications were used the 3 (three) types of surfactants, anionic, cationic and ampholitic with surfactant concentration were used 45%, 60% and 75% respectively of the total weight of 300 grams adsorbent. The contact time of variation between 10-90 minutes with stirring speed of 50, 70 and 90 rpm respectively. Mn metal concentration analysis done by Atomic Absorption Spectrometer (AAS) (Shimadzu UV-1800) whereas the determinations of the characteristics for wavelengths before and after treatment are used Spectrophotometer Fourier Transform Infra Red (FTIR) IR Prestige-2, and organokaoline surface morphology using SEM. The results of the study organokaoline successfully reduce Mn metal ions in water till 95% of the initial concentration of 10 mg/L. Testing FTIR spectra showed differences as well as the SEM test looks morphology before and after the absorption of the metal ion Mn.
