The influence of different reaction parameters such as pH, hydrogen peroxide, ferrous sulfate, and the RR 120 concentration on the oxidative degradation of RR 120 have been appraised. The optimal reaction conditions were determined and it was found to be pH = 3.50, [H2O2] = 1.1×10-3 M, [Fe2+] = 1.0×10-4 M for [RR 120] = 7.5×10-5 M. Under optimal conditions, 96.0% decolorization efficiency of dye in aqueous solution was achieved after 15 min of reaction. The effect of azo bond loading (Lazo bond), from 0.25 to 1.0, and pH values from 2.5 to 5.0 were estimated on RR 120 color removal kinetic rates. A correlation between the kinetic of the color removal rates (ln k2) versus Lazo bond was carried out at the different pH levels. The color removal rate increased linearly with decreasing Lazo bond, in the order of pH: 3.5 > 5.0 > 2.5. All the experimental data were analyzed using the first and second-order kinetic models. The second-order provides the best correlation of the data. 67% Chemical Oxygen Demand (COD) removal efficiency of the RR 120 were achieved after 15 min of reaction by fixing the initial H2O2/Fe2+ molar ratio, COD loading factor (LCOD), and pH at 11, 0.25 and 3.5, respectively. Also, the effects of various inorganic anions (such as Cl−, SO42-, CO32-, etc.) on the oxidation efficiency of Fenton were studied. This study can benefit planners who deal with contaminated textile wastewater using chemical treatment by advanced oxidation technologies.","PeriodicalId":255225,"journal":{"name":"Journal of Al-Nahrain University of Science","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121144947","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}

Antitumor activity of total extracted alkaloid of this plant have been studied, there are few studies that examine the properties of the total extracted alkaloids. Thus the objective of this project is to investigate cytotoxic effects of total alkaloid extracted from C. majus against Human colon cancer cell line. Powdered plant material was extracted with methanol by using Soxhlet installation. The extract subjected for acid-base extraction and purification with chloroform to obtain total alkaloids. Cytotoxicity effect of total alkaloids was estimated using MTT-assay in addition to the determination of apoptosis/necrosis FITC Annexin V /PI assay and Cell Cycle Analysis by Pi Staining. It was found that Chelidonium majus contain high amount of total alkaloids where the yield of total extracted alkaloids was about (2.146 %) of total dried weight. The total extracted alkaloids from C. majus showed high significant cytotoxicity effect on (HCT-116) cell lines which was in a dose dependent way, where the IC50 was (67.43 µg/ml). Annexin V-FITC assay showed that total alkaloids from C. majus is strong inducer of apoptosis in HCT-116 cell line. While, the cell cycle arrest evaluation showed that the extract arrests cell cycle progression by significantly restricting cells in different phases (G1, S, G2/M) in a dose dependent way. It is concluded that the plant contains a large quantity of total alkaloids. The total extracted alkaloids showed cytotoxic activity against colorectal cancer (HCT-116) cell line which was in dose dependent manner indicating that the extract could be used in cancer therapy.","PeriodicalId":255225,"journal":{"name":"Journal of Al-Nahrain University of Science","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133666074","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 refers to the integration of a large number of appropriate cations and anions even of the large “salt like” {M(SO4)}16 rings (M = K+ or NH4+) based on the cooperative/synergetic activation of silent receptor sites. An even more remarkable consequence of the flexibility behavior of the molecular giant wheel-shaped molybdenum-oxides of the type {Mo176} and {Mo154}: the possibility of the integration of Cu2+ as tetrahedrally coordinated divalent cations at the same wheel area. In this study and in order to make the phenomenon as a general, the incorporation of ions into giant molybdenum-oxide cluster was expanded to involve the integration of some other cations (Fe2+, Co2+, Ni2+ or Zn2+) or salt like ring{Tl(SO4)}16. Uptake and almost half of the 16 {Mo2} units the parent ring structure is maintained in the following resulting hybrids {(Mo146) (K(SO4))16} 1compound, {(Mo146) (NH4(SO4))16} 2 compound and {(Mo146) (Tl(SO4))16} 3. Moreover, the integrating of a tetrahedrally coordinated divalent cation like Fe2+, Co2+, Ni2+ or Zn2+ in addition to Cu2+, at the same wheel area (after releasing six {Mo2}-type building blocks of the parent wheel-shaped cluster) produced hybrid compounds with the general formula: [H4MIIn MoV28MoVI114O432(H2O)58]-26+2(n-5) (where MII= Fe2+, Co2+, Ni2+ or Cu2+, n=5, but with Zn2+, n=6) compounds (4–8). The result corresponds to the extreme flexibility of molybdenum-oxide building block linking resulting in the formation of a huge variety of structures from “molybdate” containing solutions (a unique molybdenum-oxide diversity phenomenon). The prepared compounds were characterized by CHN, Cit.Tit for the determination of the number of the MoV centers, spectroscopic methods (IR and UV-Vis) and X-ray crystallography (determination of the characteristic unit cell dimensions).","PeriodicalId":255225,"journal":{"name":"Journal of Al-Nahrain University of Science","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127868385","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}
