Adsorption and inhibitive properties of ethanol extracts of Musa sapientum peels as a green corrosion inhibitor for mild steel in H2SO4
The inhibition of the corrosion of mild steel by ethanol extract of Musa sapientumpeels in H2SO4 has been studied using gasometric and thermometric methods. The results of the study reveals that the different concentrations of ethanol extract of M. sapientum peels inhibit mild steel corrosion. Inhibition efficiency of the extract is found to vary with concentration, temperature, period of...

Oxovanadium (IV) esters of ciprofloxacin: Their characterization and potentiometric study
The reaction between ciprofloxacin and VOSO4.3H2O in 1:1, 1:2 and 1:3 molar ratio in methanol was investigated at 20ËšC, 0ËšC and -10ËšC. In various pH conditions the different complexes which are formulated as VO(H2O)3L, VO(H2O)L2 and VL3 have been formed by titration of VOSO4.3H2O with ciprofloxacin in the presence of NaOH. These complexes have been characterized by IR spectroscopy. The order of...

Physico-chemical analysis and toxicological studies of Madaran sukudai (a local drink in Northern Nigeria)
Physico-chemical analyses have been carried out on concentrated Madaran sukudai, diluted M. sukudai and pure formalin. Both the infrared and UV-visible spectroscopic studies on the three solutions revealed that the madaran sukudai is essentially a dilute formalin solution. Toxicological studies of the effect of M. sukudai on the white albino rats were also carried out. The results showed that there was significant...
