Abstract:
This work has developed a convenient way of constructing wood cellulose and clay green composite hydrogel as efficient adsorbent of colored organic effluent. The optimized cellulose/montmorillonite(MTM) hydrogels showed excellent methylene blue (MB) absorption with the maximum capacity of adsorption (Qmax) of 277 mg/g, which is not only higher than MTM alone, but also higher than many other natural clay composite adsorbents. Adsorption mechanism and kinetic studies that the physisorption was a major processing in MB absorption and the adsorption mainly occurred in the internal structure of composite hydrogel. This indicated that the MTM embedded inside played the most critical role for the MB dye adsorption. Owing to its biodegradability and excellent adsorption capacity, cellulose/MTM hydrogel has good potential for colored organic effluent treatment. The simple procedure and cost effective wood cellulose as raw material for the composite absorbent construction presented in this research are favorable for industrial applications.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
