This study aimed to use an extract from its exoskeleton in treatment of water copper toxicity, the most abundant heavy metal along aquatic habitats. Three different composite films were prepared from the exoskeleton of Procambarus clarkii, and used for wastewater remediation. In this study, film efficiency towards copper ions was determined and showed that the maximum removal was achieved by the third one which is incorporated by a Porogen substance, and increased with increasing contact time until reaching equilibrium where removal rate remains constant. The increase in temperature (25-55°C), reduces the efficiency of the all three films in removing copper ions, the best temperature value for removing copper ions for all three films, was 25°C. The thermodynamics and kinetics was studied for the third composite modified film, the adsorption process was exothermic and the kinetic model, pseudo second order is fitted to it. Adsorptive sites energy of the modified composite film was studied by applying two isothermal models; Langmuir and Freundlich models, Langmuir model was fitted to it.","PeriodicalId":12075,"journal":{"name":"Fayoum Journal of Agricultural Research and Development","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73078857","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}

Animal mortality, body weight hematology, micronucleus assay and comet assay were investigated. The findings showed that TiO 2 -NPs significantly reduced the body weight, and the results indicated a change in all blood parameters due to the stress response of TiO 2 NPs. Hematological results revealed that the red blood cell count, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, white blood cell count, and platelet count of TiO 2 NPs-treated male rats were altered compared to the control group. However, the WBC of rats was elevated with increased doses of NPs compared with the control. There were no significant differences (P>0.05) in hematological parameters. Comet assay and micronuclei test results show a dosage-dependent increase in DNA fragmentation, which was supported by an increase in percentage of DNA that is tailed, length and intensity of DNA tails, and tail moment, especially at the 300mg/kg dose. According to the findings, the frequency of micronucleated cells has increased.","PeriodicalId":12075,"journal":{"name":"Fayoum Journal of Agricultural Research and Development","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73138148","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}
