In previous studies much research has reported the determination of applications of TiO2 (rutile and anatase), ZnO and Ag nanomaterials onto various textile surfaces, but in this study for the first time application to denim fabric and testing of the finished fabric for antimicrobial activities of these nanomaterials was investigated. The presence of nanoparticles on dyed denim fabric surfaces was confirmed by Scanning Electron Microscope (SEM). The nanomaterial-impregnated denim fabric (100% cotton) showed significant antibacterial activity against Staphylococcus aureus, Escherichia coli and Escherichia coli isolated from pasta. Additionally, the UV tests indicated excellent improvement in the UV absorbing activity of the TiO2 (rutile and anatase), ZnO and Ag nanomaterial-treated fabrics.

In this study, iron cyclohexanedicarboxylic acid was synthesized under refluxing conditions. The structural characterization of the complex was performed by using physico-chemical and spectroscopic methods. The effect of pH on division constant () and extraction percentages (% E) in water and organic phase was investigated with the extraction method. At the end of the experiment, most of the Fe 2+ ions in the water phase at pH=7.5 passed into the organic phase. Above this pH, the extraction percentage decreased because of the transition from water phase to organic phase. Iron cyclohexanedicarboxylic acid was extracted with ether, petroleum ether, benzole and carbon tetrachloride from aqueous solution and microbial activities of the complex were studied. The activity data showed that iron cyclohexanedicarboxylic acid has an important antibacterial and antifungal activities.
