Post-deposition annealing effects on nanomechanical properties of granular TiO2 films soda-lime glass substrates were studied. In particular, the Na diffusion films' mechanical examined. photocatalyst films, 330 nm thick, prepared by dip-coating using a sol, and annealed between 100 °C 500 °C. Film's morphology, physical characterized atomic force microscopy, X-ray photoelectron spectroscopy, diffraction, differential thermo-gravimetric analysis, nanoindentation. Contrary to expectations,...
In this study the kinetics of stibnite dissolution in (Na2S+NaOH) aqueous media has been investigated. The dependence controlling mechanism and antimony rate have studied with respect to Na2S NaOH ratio, solution temperature, powder size solid liquid ratio. All results (based on f(X)-t curves) illustrated that ash layer diffusion could be via using shrinking core model. Also, XRF SEM analysis confirms is nonmetallic possibly Silica. addition to, reaction was order 2 based numerical apparent...
ABSTRACTDue to the scarcity of water in many parts world, wastewater generated by hydrometallurgical processes has been recognized as a valuable resource for recovery or reuse. A method reusing raffinate leaching low-grade oxide copper ore counter-current process was evaluated. In first stage investigation, influential factors on leaching, such amount acid consumed (200–400 g/kg ore), initial iron concentration (5–25 g/L), liquid-to-solid ratio (2–10 mL/g), and duration (15–75 min), were...
