“…This result occurred because the iodometric method that was used to detect the oxidation species, was not selective for O 3 . The iodometric method also was also affected by the presence of nitrogen oxides dissolved in water (Tichonovas, 2013). Iodide was oxidized to iodine by NO 2 , which was reduced to NO.…”

“…Due to the structural stability and complexity of dye molecules, they represent a real threat to the environment and human health (Njoku et al 2014). The traditional methods for the removal of dyes from the wastewater include air flotation (Liang et al 2014), sorbents adsorption (Tichonovas et al 2013), membrane separation (Türgay et al 2011), extraction (Bakheet et al 2013), chemical oxidation (Kumar et al 2013), electrochemistry (del Río et al 2011), froth floatation, and biological methods (Liu et al 2006). However, owing to the fact that adsorption is simple and can be carried out in a small area, approaches based on adsorption have been increasingly considered to remove dye from wastewater (Kaouah et al 2013).…”

aBiochar from peanut shell was used as the precursor for the preparation of porous biochar by KOH activation. The pore structures of porous biochar also were characterized by scanning electron microscopy (SEM) and N2 adsorption/desorption. The adsorption performance for the removal of methylene blue (MB) was deeply investigated. The effects of impregnation ratio (KOH/biochar: w/w), activation temperature, and activation time on the removal of methylene blue by porous biochar were evaluated. In addition, the effects of initial MB concentration and pH value on the adsorption process were also studied. The optimum conditions for preparing porous biochar were obtained with 1.5:1 of impregnation ratio, 800 °C of activation temperature, and 90 min of the holding time in activation. Results indicated that the adsorption capacity was high even at higher initial MB concentrations. The adsorption process followed pseudosecond-order kinetics. The experimental adsorption isotherm was found to be best fitted with the Langmuir model, which implying that the adsorption of MB by porous biochar proceeded as a monolayer adsorption, and the maximum monolayer adsorption capacity of MB was 208 mg•g -1 .

“…The organic groups present in dyes results in mortality, genotoxicity, mutagenicity and carcinogenicity , so it is necessary to remove these organic pollutants from wastewaters before discharge to major water bodies (e.g., lakes, rivers or oceans). Different processes which are involve in textile production like dyeing and washing results in the production of large quantities of wastewater along with different toxic chemicals [3].…”

In this study the radiation-induced degradation of crystal violet (CV) dye under various experimental conditions has been investigated. D 0.5 , D 0.9 and D 0.99 values suggests that lower doses are required for 50%, 90% and 99% removal of CV dye when the sample solution contains excessive amount of• OH radicals. The removal efficiency of CV dye in terms of G-values was also calculated under each reaction conditions. The results showed that• OH radicals are playing effective role in the degradation of CV dye as compared to e aq -and • H radicals. The gamma irradiation process effectively degraded CV dye at all pH values. The organic byproducts were examined and accordingly degradation pathway was proposed.
