Adsorption of Organic Substances on Modified Montmorillonite, Cloisite 10A, 15A, 20A, 25A, and 30B

Abstract:

Clay modified with organic surfactant, Cloisite 10A, 15A, 20A, 25A, and 30B act as effective adsorbent in organic wastewater applications. The experiment was tested using wastewaters from removal of skim NR from concentrated NR industry. The ability to remove organic contaminants from aqueous solution, based on different molecular structures of organically modified clays, was evaluated using UV/VIS spectroscopy, chemical oxygen demand (COD), biological oxygen demand (BOD), suspended solid (SS), total dissolved solid (TDS), total solid (TS) and total kjeldahl nitrogen (TKN). In addition the mechanical properties of nanocomposites product obtained from coagulating method were determined by tensile testing. It reveals that mechanical properties of nanocomposites were improved when compared to the original skim rubber. The thermal stability and the composition of the coagulated skim rubber-organoclay nanocomposites were determined by thermogravimetric analysis.
