“…As indicated in Table , the influence of initial concentration on the rate constant, the rate constant of waste removal does not remain constant when the initial concentration is changed. The reason behind this is due to secondary photochemical processes that occur during photocatalytic degradation and also a change caused by the quenching process due to excimer formation, in which some intermediates absorb light and re-emit it as heat without initiating semiconductor photocatalysts, resulting in photons not reaching the photocatalyst’s surface. ,,,, …”

Experimental design DoE (box behnken design BBD) and statistical analysis approaches were employed to determine the effect of Congo red dye (C.R) concentration, photo catalyst dose (Fe+2) and follow of oxygen gas as an oxidant on the degradation of C.R. The results show that the concentration oppositely affects the degradation yield whereas the remaining two factors show positive effect, throughout all experiments oxygen molecule shows crucial role in their positive effect with p-value about 0.01 which is very significant value. The accepted regression model was linear with significance p-value 0.032 that mean all factors show good agreement in linear relationship and the interactions was not important. Degradation kinetics was also applied to investigate the effect of increasing dye concentration on degradation rate constant with and without photo catalyst dose and oxidant (O2). It appears that the degradation of peak at 498nm is second order The result was in good agreement with that of statistical analysis that are 0.0435, 0.0545 and 5.4 M- min- with photo catalysis 12, 8 and 4 PPM dye, 4O2 mL/min,20PPM Fe+2 respectively, in case without photocatalyst the results were 0.0025 and 0.0207 M- min-with 12 and 4 PPM in turn.

“…Several methods in wastewater treatment technology have been performed to degrade or remove organic contaminants from aqueous solutions including electrochemical treatment, ozonation, photo degradation, adsorption, ion exchange and evaporative recovery [5][6][7][8][9][10][11][12][13][14]. Adsorption method has been proved by researches to be an effective and one of the extensively used approaches for the removal of organic and inorganic pollutant from wastewater [15][16][17].…”

Pristine and oxygen functionalized multi-walled carbon nanotubes were used as adsorbent for removal of Methyl Orange (MO) dye. The adsorption was carried out under different pH values. The analysis of results indicated that the adsorption characteristics of the MO dye by pristine carbon nanotubes (P-CNTs) and oxygen functionalized carbon nanotubes (O2-CNTs) are highly influenced by the pH of the medium. The study report that the best pH medium of solution for the adsorption of MO on both CNTs was acid medium. The point of zero charge (pzc) of O2-CNTs and P-CNTs were determined as function of pH. The pzc of P-CNTs and O2-CNTs are found to be 4.7 and 3.9, respectively. The adsorption data have been analyzed using Langmuir and Freundlich. Fitting the equilibrium adsorption data by Langmuir and Freundlich models shows that experimental data well explained by the Langmuir equation.
