Titanium and its alloys have superior electrochemical properties compared to other alloy systems due the formation of a protective TiO2 film on metal surfaces. The ability generate oxide layer will depend upon type be used. aim this work was characterize corrosion behavior titanium Ti-CP2 Ti-6Al-2Sn-4Zr-2Mo, Ti-6Al-4V, Ti Beta-C. Samples were anodized in 1 M H2SO4 H3PO4 solutions with current d...

A novel sensitive and relatively selective kinetic method is presented for the determination of V(V), based on its catalytic effect on the oxidation reaction of Ponceau Xylydine by potassium bromate in presence of 5-sulfosalicylic acid (SSA) as activator. The reaction was monitored spectrophotometrically by measuring the decrease in absorbance of Ponceau Xylydine at 640 nm between 0.5 to 7 min ...

We present the synthesis of Activated Carbon (AC) by pyrolysis Banana (Musa Acuminate) Stem Waste (BSW), and ability obtained AC for adsorptive removal Pb(II) ions from water. Importantly, was performed at 750°C 2.0 h in presence high surface area producing chemical activators such as NaOH, LiOH, H3PO4, ZnCl2, KOH. BET-surface areas produced with KOH were determined to be 908, 1531, 1670, 2245,...
