Adsorpsi ion Na + dan K + dengan karbon aktif merek Norit.

Abstract

Adsorpsi Ion Na4 Dan K4 Dengan Karbon Aktif Merck Dan Norit Telah dilakukan penelitia adsorpV. karbon aktif merck dan norit terhadap ion Na dan K . Adsorpsi ini dibandingkan dengan adsorpsi terhadap metilen blue. Untuk mempelajari kemampuan adsorpsi karbon aktif jugs telah ditentukan luas permukaan, distribusi pori, serta sifat kimia permukaan karbon aktif merck dan norit. Untuk mengetahui jumlah adsorbat logam yang teradsorpsi dilakukan analisa kuantitatif dengan spektroskopi serapan atom, sedang adsorbat metilen blue dengan spektroskopi UV-VIS. Luas permukaan dan distribusi pori karbon aktif diketahui dengan slat penganalisa luas permukaan BET. Sifat kimia permukaan karbon aktif diketahui dengan membuat spektra IR dari karbon aktif sebelum dan sesudah adsorpsi. Luas permukaan karbiln aktif merck 2dan norit masing-masing 782,728605 m/g dan 9,275572 m /g. Karbon aktif Merck dan norit mengadsorpsi metilen blue dengan balk masing-masing sebesar 4,700 ppm dan 4,467 ppm (pada konsentrasi larutan metilen ble 5 ppm). Karbon aktif merck dapat mengadsorpsi ion K sebesar 1,106 ppm (pada konsentrasi larutan kalium 3 ppm), tetapi tidak dapat mengadsorpsi ion a . Karbon aktif norit dapat mengadsorpsi ion Ma sebesar 0,703 ppm (pada konsentrasi larut4 natrium 3 ppm), tetapi tidak dapat mengadsorpsi ion Ma . The study of adsorption of Ma+ and LK+ ions on merck and norit activated carbon had been done.These adsorption were compared to adsorption of metilen blue. Besides of studying the adsorption of activated carbon, the surface area, the pore distribution and the chemical nature of the surface area of activated carbon had been determined. The quantity of ions that had been adsorbed on activated carbon was determined by using Atomic Adsorbtion Spectrofotometri, whereas the number of metilen blue that adsorbed on activated carbon was determined by using Spectrofotometri UV--'CIS. Merck a9d norit activated2 carbon had surface area of 782,728602 m /g and 9,275572 m /g respectively. Metilen blue was well-adsorbed on Merck and norit activated carbon. The amount of metilen blue that had been adsorbed on merck and norit activated carbon was 4,700 ppm and 4,467 ppm (from 10 mL of 5 ppm metilen blue) respectively, per 100 in activated carbon. Na ion that had been adsorbed amounts to 0,703 ppm pTr 100 mg norit activated carbon (from 10 mL of 3 ppm Na ), but it wal not adsorbed on merck activated carbon. The number of K ion that had been adsorbed was 1.106 ppm per 100 mg merck activated carbon (from 10 mL of ppm K ), but norit activated carbon did not adsorb K ion.
