In water UV-irradiation; | General procedure: The photocatalytic activity of CuAu-ZnO-Gr was evaluated by the degradation of MO, MB, IN, SY, and TT in quartz beaker under sunlight irradiation, which was allowed by the use of an external sunlight simulator (CHF-XM-500W, 15 A). The photodegradation of synthetic colorants MO, MB, IN, SY, and TT in the presence of CuAu-ZnO-Gr was similar to those discussed recently to mimic photocatalytic degradation of organic pollutants [20-22]. In this work, 50mL of MO (2×10-5molL-1), MB (1×10-5molL-1), IN (4×10-5molL-1), SY (1×10-5molL-1), and TT (1×10-5molL-1) test solution were prepared firstly. Then, these test solution were treated with 0.2mgmL-1 of CuAu-ZnO-Gr respectively and next were agitated for 30 min in the dark to achieve the adsorption and desorption equilibrium. Because of the small amounts of catalyst, 30 min was enough to quickly reach the adsorption and desorption equilibrium. Subsequently, the above suspensions were irradiated with the simulated sunlight. After a certain time interval (5 min for MO, 2 min for another colorants), 2 mL of the suspension was taken, and the catalyst was separated by centrifugation to obtain a clear liquid from which UV-vis spectra was measured. In a similar way, CuAu-ZnO, Au-ZnO, ZnO-Gr (only for MO), and ZnO were used in the degradation of MO, MB, IN, SY, and TT. | |

With Oxone for 1h; Irradiation; | 2.4. Irradiation experiment All photocatalytic experiments were carried out under similar conditions of sunny days between 11 am and 2 pm. An open borosilicate glass tube of 50 mL capacity, 40 cm height, and 20 mm diameter was used as the reaction vessel. The suspensions were magnetically stirred in the dark for 30 min to attain adsorption-desorption equilibrium between dye and NiS/TiO2. Irradiation was carried out in the open-air condition. Fifty milliliters of dye solution with NiS/TiO2 was continuously aerated by a pump to provide oxygen and for the complete mixing of reaction solution. During the illumination time no volatility of the solvent was observed. After dark adsorption the first sample was taken. At specific time intervals 2-3 mL of the sample was withdrawn and centrifuged to separate the catalyst. One milliliter of the centrifugate was suitably diluted and its absorbance at 313 nm was measured. The absorbance at 313 nm represents the aromatic content of SY and its decrease indicates the degradation of dye. The intensity of solar light was measured using LT Lutron LX-10/ADigital Lux meter and the intensity was 125 x 100±100 lx. Thei ntensity was nearly constant during the experiments. | |

With nanobiochar modified triethylenetetramine In water at 25℃; Irradiation; | 2.4. Adsorptive elimination studies General procedure: 500 mg/L stock solution of tartrazine (TA) and sunset yellow (SSY)dyes were prepared in distilled water and was then diluted to 50, 75and 100 mg/L concentrations. The absorbance values of the two dyeswere determined at λ max = 433 nm for tartazine and λ max = 481 nmfor sunset yellow using UV spectroscopy instrumentation. The elimina-tion experiments were carried out at room temperature (25 °C) and the reactions were performed using automatic shaker. The elimination ofthe two dyes using NCB-TA-PC was studied under different practical pa-rameters as the inuence of NCB-TA-PC dose, contact time, initial con-centration of the dye, pH, interfering salts and temperature. | |
