The chemical composition, the morphology and the structure of raw CT and all prepared samples, were investigated by X-ray fluorescence, Fourier transform infrared spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM) to get a better understand concerning the catalytic activity behavior of Cu-CT catalyst. Different variable examined the catalytic activity of the samples obtained such as initial concentrations of dye, copper (Cu) loading, temperature and H 2 O 2 effect was investigated to enhance the MG conversion. CWPO experiments showed that 2.5% Cu-CT catalysts have the maximum catalytic activity during the degradation of MG dye. The presence of copper on CT support ameliorates the hydroxyl radicals in the reaction medium after the contact with H 2 O 2 thus enhanced the catalytic conversion of the CT pristine.

This waste has a high polluting power as well as a high antibacterial activity exerted, among others, by various phenolic compounds. In this study, the Fenton process using hydrogen peroxide (H 2 O 2 ) as oxidant and ferrous ions (Fe 2+ ) as catalyst was used to treat OMW. Box–Behnken design (BBD) based on the response surface methodology (RSM) was adopted to evaluate the effects of concentration [H 2 O 2 ], concentration [Fe 2+ ] and reaction time on the chemical oxygen demand (COD) removal, phenolic compounds (PC) removal and the residual H 2 O 2 level remaining in the solution. According to the Analysis of Variance (ANOVA), the three quadratic models that were developed using multiple regression analysis were reliable and successfully fit the experimental data with a high coefficient of determination R 2 ranging from 0,9969 to 0,9999. Optimal operating conditions based on the desirability function methodology were found to be [H 2 O 2 ] = 13,79g/l (0,4mol/l), [Fe 2+ ] = 0,55g/l (0,01mol/l) and reaction time = 5,73h. Under the values of these variables, COD removal of 88,70% and PC removal of 84,26% with no residual H 2 O 2 were predicted with a desirability value of 1.","PeriodicalId":18768,"journal":{"name":"Moroccan Journal of Chemistry","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44233127","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}

The values obtained during the determination of a few parameters (density, pH, conductivity, dry matter - moisture content, organic matter-mineral matter) show that the two materials RC and GC studied have the same physical-chemical properties. The all characterization of the two clays was carried out by XRD, XRF, FTIR, SEM/EDX and TGA. The results obtained show that the two materials have very irregular and microporous structures, a heterogeneity of the pore forms and they are contain a mixture of Kaolinite, Illite, Quartz, Calcite, and Dolomite, with the presence of Hematite only in clay RC. On the other hand, The statistical approach applied to determine the dependence relationship between the two clays was based on two tests: Student's t-test (Comparison of two means for physical-chemical parameters) and Pearson's test (contingency table for XRF analysis) in order to prove that the two materials studied are the same chemical and physical-chemical characteristics.","PeriodicalId":18768,"journal":{"name":"Moroccan Journal of Chemistry","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46295184","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}

The aim of this study was to explore 3D-QSAR approaches to propose new thiadiazole-thiazolone derivatives as Eg5 inhibitors for human mitotic kinesin. The CoMFA/CoMSIA contour maps were generated to provide the information about regions where the activity might be increased or decreased.
