Galam wood (Malaleuca cajuputi) is one of the woody plants that able to grow well in peat swamp environment South Kalimantan wetlands. Research on synthesis and characterization magnetic-hydrochar from galam bark waste for treatment sasirangan liquid has been carried out. This study aims determine characteristics hydrochar against adsorption ability waste. The results showed modification into p...

The objectives of the research were to evaluate a magnetite-based adsorption process as an alternative treatment technique for removing metals from industrial wastewaters. A composite adsorbent was prepared b precipitating sorption, magnetic separation, and desorption process to recover Cr or Zn from solution The process was effective, but performance decreased when the adsorbent was recycled. ...

bioleaching of spent refinery processing catalysts using adapted indigenous strains ofacidithiobacillus ferrooxidans to recover ni and mo, and the separation of ni from bioleaching liquor usingiron magnetic nanoparticles were optimized in this study. bioleaching optimization was performed usingcentral composite design (ccd) method to optimize temperature (32 to 38oc), initial ph (1.5 to 2), par...

Dyes in the textile industry are the most significant source of pollutants, which cause damaging effects to people’s health. Reactive black 5 (RD5) is an anionic color that is currently used in the textile industry. This study is designed to provide the strategies to synthesize and characterize the new family of functionalized magnetite nanoparticles via a chemical co-precipitation method with ...

toluidine blue o (tbo) is a cationic dye which is extensively used in the industries. in the present paper a simple and efficient wet chemical method was introduced for removal of tbo from waste aqueous solution. magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

The application of poly (vinyl alcohol) (PVA) in an unmodified form as an adsorbent for methylene blue (MB) dye removal in waste water at 303–333K was investigated. Effects of operational parameters such as adsorbent dosage, initial dye concentration and pH were determined for optimum conditions for maximum dye removal. Results obtained showed that dye removal efficiency increases as the amount...

A 5’-deoxyadenosylcobalamin-agarose adsorbent has been prepared for the purification by affinity chromatography of enzymes which require 5’-deoxyadenosylcobalamin as a coenzyme. The synthesis involved the covalent attachment of cyanocobalamin to agarose through a 12 carbon chain. This hydrocarbon chain was attached to the corrin nucleus by reacting diaminododecane with cyanocobalamin e-carboxyl...

The adsorption of Triton X-100 in aqueous solution on the granite sand has been investigated to evaluate its ability as an adsorbent. Various parameters such as agitation time, adsorbent dose, adsorbent size, initial concentration of adsorbate, pH, temperature, and effect of interference ions were studied on the laboratory scale to establish optimum conditions for the removal of TX-100 from the...
