Abstract

This paper assesses certain heavy metal concentrations in borehole water within Zuru Metropolis, Kebbi State. Utilizing rigorous sampling and analytical methods, the study aims to provide insights into the potential health risks associated with heavy metal exposure in the local water supply. Twenty different borehole water samples were assessed for Zn, Pb, Hg, Mn, Cr and Cd levels (mg/l). The results revealed that only few boreholes water samples had concentration levels of heavy metals that are not within WHO recommended levels. While chromium and cadmium levels are below detection limits .The findings contribute to the understanding of water quality in the region, offering valuable information for public health interventions and water management strategies.

Abstract

The study explores the chemical composition of neem seed oil, highlighting its potential for commercial biodiesel production and various industrial applications. The oil, with a liquid state, pale greenish-yellow color, and pleasant odor, yielded 32.1%, surpassing industrially extracted oils like soybean and cottonseed. Factors influencing its composition include seasonal variations, geographical origin, genetic disparities, growth stages, plant segments, and postharvest processing. Despite these, neem seeds meet the required oil content percentage for large-scale industrial biodiesel production. However, challenges like high free fatty acid content and elevated acid values necessitate acid esterification before alkaline transesterification, potentially increasing production costs. The study also highlights the importance of appropriate seed processing practices to optimize oil yield and quality.

Abstract

Biodiesel production from neem seed oil and performance evaluation of three selected catalyst was investigated. Neem seed oil was used for its suitability as feedstock for biodiesel production. The oil was extracted using soxhlet extraction method using n- hexane as a solvent and yielded 42.1%. Biodiesel was produced according to box behnken design in response surface methodology, to study the effect of experimental variables such as methanol to oil ratio, catalyst concentration, temperature and reaction time. Three (3) catalysts were used during the process namely CaO, MgO and ZnO. The model shows the highest of biodiesel yield of 89% w/w using MgO at 9:1 methanol to oil ratio, catalyst concentration of 1.1% w/w, reaction time was 120 minutes, and temperature was kept constant at 600C. ZnO performance on the transesterification of neem seed oil to biodiesel yielded 88% w/w at 6:1methanol to oil ratio, 0.8% w/w catalyst concentration and 90 minutes was the reaction time. Similarly CaO performance on the trasesterification of neem seed oil to biodiesel yielded percentage of 84 % at 6:1, catalyst concentration of 0.8% w/w and reaction time was 90 minutes. Methanol to oil ratio and catalyst concentration has significant effect on trasensterification of neem seed oil to biodesel than reaction time among others studied. The physiochemical properties of produced biodiesel was analyzed and characterized for its Fatty Acid Methyl Ester (FAME) profile using GCMS. Fuel properties of the biodiesel obtained are within the recommended standard of ASTM and suitable to be an alternative source of fuel.
