In this paper, the low-cost and practical adsorption for removing methylene blue (MB) dye has been developed by using recoverable natural zeolite that was magnetized with Fe3O4. The magnetization was conducted by co-precipitation technique. The adsorbents obtained from the magnetization were...

Metallurgy and recovery of gold in electronic waste sometimes involve the reduction of tetrachloroaurate ion (AuCl4-) to elemental gold form. Currently, for the reduction of tetrachloroaurate ion, people use reducing agents such as hydroquinone and sodium borohydride. Photocatalysts of Fe3O4/SiO2...

ºCIn this study, potential of useful products recovery was investigated from waste tires that completed the physical life by virtue of pyrolysis process. Disposal of waste tires, which is one of the global environmental problems, continues the presence thereof as a serious problem, especially in...

The photocatalytic activity of Mn doped TiO 2 for the ozonation of tetradifon pesticide in aqueous solution was studied. Various loadings of catalysts Mn/TiO 2 (1%, 2.5% and 5%) was prepared and characterized by standard analytical techniques. Photocatalyzed ozonation with 2.5% Mn/TiO 2 yielded 100%...
