Presence of colour in water will make it unsuitable for human consumption. Textile industries have the major role in imparting colour in natural water bodies as their outlets are opened to them. These industries rely upon azo dyes as it impart brilliant colour to fabrics. But its presence in water bodies creates serious problems. Structure of an azo compound is a very important factor to be con...

Microwave-assisted catalytic oxidation technology has become an effective for rapid removal of organic pollutants in wastewater. In this research, the methyl orange (MO) from aqueous solution by CuFe2O4 loaded on carbon nanotubes (CuFe2O4/CNTs) under microwave irradiation was studied. The effects different loadings (1:2, 1:4, 1:8) dielectric loss, magnetic loss factor, and reflection composite ...

In the present study, a Cameroonian smectite was used as an adsorbent to model adsorption kinetics of three textile dyes (malachite green, methyl red and acid blue 74) from aqueous solution in batch system. The effects pH temperature were evaluated on capacities, times required reach equilibrium mechanisms involved. It can be seen that, although are independent medium, process studied is favour...

In recent years, although the China government has carried out some serious investigation and effort to shut down the indigenous coke-production, it has not achieved effective control. The main image TM754 (red, green, blue) false color composite of Shanxi province in northern China was chosen as the study area in this paper. The indigenous coke-production sites are regions which appear red and...

In Int. J. Biol. Macromol., volume 81, three articles present the idea f a “pseudo-first-order-model”. These are: “Surface ion-imprinted mino-functionalized cellulosic cotton fibers for selective extracion of Cu(II) ions” [1], “Adsorption of methyl orange (MO) by r(IV)-immobilized cross-linked chitosan/bentonite composite” 2], and “A new porous magnetic chitosan modified by melamine or fast and...

This work describes the development of magnetic levitation (MagLev) to characterize the kinetics of free-radical polymerization of water-insoluble, low-molecular-weight monomers that show a large change in density upon polymerization. Maglev measures density, and certain classes of monomers show a large change in density when monomers covalently join in polymer chains. MagLev characterized both...
