Abstract:
The objective of this research is to study the possibility to use manganese oxide-coated shredded glass preparation from the cullet plant and for removal dyes and surfactants. Manganese oxide coating condition was evaluated by varying coating time, concentration of manganese chloride, comparing with leaching of manganese. Three type of dyes (Basic Yellow 1: BY1, Methylene Blue :MB and Acid Blue 45: AB45) and three types of surfactants (Triton X-100: TX100, Cetyl Pyridium Chloride: CPC and Linear Alkylbenzene Sulfonate: LAS) were selected to determine the removal efficiency and the experiments were carried out by using batch and column tests. Moreover, selective adsorption between surfactant and ionic dyes was also studied. According to the experimental results, shredded glass coating time at 10 hours and 2.5 molar Manganese Chloride provided the lowest Manganese Oxide leaching and highest adsorption capacities. In addition, BY1, AB45, MB can reach the equilibrium state at 120, 120, 180 minutes, respectively. CPC and LAS can reach the equilibrium state at 180 minutes but TX100 could not be adsorbed by the adsorbent. Adsorbents kinetic data can be described by using pseudo-second order. BY1 and CPC had highest removal efficiency at pH 9, whereas, AB45 and LAS had highest removal efficiency at pH 5, which can be explained by electrostatic interaction. Adsorption isotherms can be fitted well with Langmuir isotherm. The presence of TX-100 didnt affects to adsorption capacities of ionic dyes. While, the presence of ionic surfactants (CPC and LAS) and ionic dyes (BY1 and AB45) in bi-solution can decrease adsorption capacities of each other. The column test showed the same trend as batch test, however, adsorption capacities of column tests were lower than capacities of batch tests.
