The aim ofthis studyis to monitor and to assessthe physicochemicalwater qualityof the river Senegal during the rainy and dry season. The conventional physico-chemical parameters (pH, EC and DO), dissolved and suspended particles (turbidity and TSS), OM and nitrateswere considered in this study....

The corrosion inhibition action of sulphadoxine and pyrimethamine, which is being sold under the trade name “Antimal” as a single antimalarial drug was used as low cost and eco-friendly inhibitor for acid corrosion of mild steel monitored by means of an electrochemical technique at room...

In an effort to optimize the reaction conditions of biodiesel production from Chrysophyllum albidium seed oil, Response Surface Methodology (RSM) was applied and the effects of reaction temperature (X1), catalyst amount (X2), reaction time (X3) and methanol/oil molar ratio (X4), and their...

Equilibrium, kinetics and thermodynamic studies on the removal of Acid Red (AR88) using Ulva reticulata have been investigated. In batch experiments, the parameters studied included the effect of the dye concentration, temperature, contact time, adsorbent dosage, pH. The pseudo-first-order and...

In this paper, we determine the eccentric connectivity index and augmented eccentric connectivity index of fan graph, wheel graph, gear fan graph, gear wheel graph and their r-corona graphs.
