The main raw materials were thiourea (Tu) as a source of S and N and tetra butyl orthotitanate (TBOT). The effects of S and N amount, visible and sun light, irradiation time and different initial cyanide concentrations (50, 100, 200 and 300 mg/L) on destruction of cyanide were studied. The S, N-TiO2 film with 0.25 g thiourea showed the best cyanide destruction in visible light. The results showed that cyanide (50 mg/L) was destructed up to 94% in visible light and approximately 100% in sun light by S, N-TiO2/glass microbead. The results also indicated 85% and 94% destruction in visible and sun light respectively by S, N-TiO2/scoria stone within 4 h. Finally, the S, N-TiO2 stabilized on glass microbeads can be effectively implemented as a new method for treatment of wastewater containing free cyanide under sun light.","PeriodicalId":14870,"journal":{"name":"Journal of Advanced Oxidation Technologies","volume":"30 1","pages":"274-284"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75267828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This procedure attempts to determine the effect of lignin-degradation products on ethanol fermentation during the bioethanol production process. Results indicate that the optimal oxidation conditions were pH5.0, 25°C, ZVI concentration of 1.0 g/L, and PS concentration of 1.5 g/L based on 0.1 g/L vanillin as the model of the lignin-degradation products. The oxidation effect of the eight other major lignindegradation products on the optimal conditions was also studied. Results show that their oxidation removal efficiency values were remarkable. Except for vanillin (99%), vanillic acid (97%), 4-hydroxybenzaldehyde (93%), and 4-hydroxybenzoic acid (81%), the removal efficiencies values of the five other lignin-degradation products (i.e., syringaldehyde, syringic acid, 3,4dihydroxybenzoic acid, p-coumaric acid, and ferulic acid) were all 100%. The dominant active species during the advanced oxidation process was sulfate radicals. Therefore, the ZVI/PS system is a suitable approach for the oxidation removal of lignindegradation products.","PeriodicalId":14870,"journal":{"name":"Journal of Advanced Oxidation Technologies","volume":"31 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85938979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acid Red 51 (erythrosine E127) and C.I. Acid Blue 74 (indigo carmine E132) by sonocatalysis using an ultrasonic frequency of 37 kHz and a power of 150 W in the presence of heterogeneous catalysts ZnO and peroxide hydrogen (H2O2). The adsorption process for the two dyes on the ZnO nanocrystalline which satisfies the Freundlich model appears not effective because the elimination of the two food dyes does not exceed 35%. In order to improve the removal, the sonocatalytic process (AD-OX) has been investigated. At this purpose, effect of operating parameters such as initial dye concentrations, H2O2(0-0.75M) and initial pH on the sonochemical degradation was investigated. It was observed that when the adsorption-catalysis was assisted by the ultrasonic and H2O2 a considerable yields has been achieved and about 86% and 97% of E127 and E132 were removed for 10 mg L-1and 50 mg L-1respectively. To understand the behavior of dye degradation, structure of the zinc catalyst before and after the sonocatalytic process was characterized by meanX-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM).Results showed thatthe ZnO particles before and after sonocatalysis were crystallized in the hexagonal wurtzite phase and the size distribution indicates that most of the particles are in the range of 300 and 600 nm. Finally, ADMI and COD analysis were performed in order toquantify the residual color in solution and evaluate the efficiency of the dye mineralization. Results showed that the treatment of food dyes by US-ZnO-H2O2process increased color degradation (ADMI)and mineralization efficiency (COD) by more than 50% and 76% respectively.","PeriodicalId":14870,"journal":{"name":"Journal of Advanced Oxidation Technologies","volume":"32 1","pages":"10-20"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74801305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
