“…(Robinson et al, 2001;Ma and Yao, 1998). Kim et al (2002) observed that the treatment of insoluble dyes from wastewater using conventional adsorption method is not possible. The coagulation method which is effective for treatment of insoluble dyes from wastewater is not so effective for soluble dye (Anjaneyulu et al, 2005).…”

Methylene blue (MB) and rhodamine B dyes (RB) were degraded from water using zirconium oxide (ZrO 2) and zirconium oxide/graphene composites (ZrO 2 /GR) as photocatalyst. The photocatalytic efficiency was calculated from absorption spectra obtained using UV-visible spectroscopy. It has been observed that photodegradation time as well as photocatalytic efficiency increase with the concentration of catalyst up to a certain limit after which effect was reversed. The degradation was studied as a function of pH also. It was found that photocatalytic efficiency was more in alkaline medium than acidic medium. Degradation of RB takes place at higher value of pH as compared to MB. The degradation time for MB was 1 h using ZrO 2 which get reduced to 32 min using ZrO 2 /GR composite and for RB it reduced to 40 min (using ZrO 2 /GR) from 80 min (ZrO 2).

“…The main modification in the characterization procedure proposed was to assume a simple discrete distribution function to represent a number of pseudospecies with the same Freundlich exponent [29,30]. Similar to the continuous function [33], the initial concentration of each pseudospecies was assigned by a binomial function in terms of Freundlich constant.…”

“…Coagulation is effective for the treatment of insoluble dyestuff wastewater but not so effective for soluble dyestuff wastewater [7]. The adsorption method has difficulties in the treatment of insoluble dyestuff wastewater and it is very difficult to find the desorption process [8,9]. The chemical method is used to oxidize organic materials using oxidizing agents such as ozone, H2O2, UV light or combinations of such oxidants, which are known as Advanced Oxidation Processes (AOPs).…”

In this study, the characteristics of colour and chemical oxygen demand (COD) removal of azo dye by ozonation and biological treatment were evaluated for applying in industrial azo dye effluent treatment. Reactive Red 120 has been selected from among azo dyes due to its high solubility in an aquatic environment. The experimentation was arranged in two stages: during the first, only ozonation was performed, while, during the second stage, ozonation was integrated with biological treatment of completely mixed activated sludge (CMAS). COD removal was contributed simultaneously by the ozonation and biological treatment mechanism at lower ozone doses. However, it was significantly the result of direct oxidation at higher ozone doses. Ozonation of dyes usually leads to small organic molecular fragments that lead to a residual COD. The biological treatment is more efficient at mineralizing the by-products of the ozonation, but less efficient at colour reduction than the ozonation process itself. Thus, COD resulting from these small newly formed molecules can be further degraded by biological treatment. Therefore, ozonation should be applied at a medium ozone dose as a pre-treatment for a combined ozonationbiological treatment for azo dye removal.
