Unmodified and aminated chitosan were used for the removal of phosphate from aqueous solution. The unmodified and aminated crab shell chitosan were characterized by using infra-red spectrophotometry, scanning electron ...

Pangolin and Alligator have been of great medicinal values to traditional practitioners in certain African countries. Pangolin and Alligator integuments were extracted and extracts were subjected to chemical investigation ...

Coulometry is a technique in analytical chemistry that determines the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced. A coulometer ...

Soil as a key component of the environment serves as a storage medium for resources. However, it also accumulates pollutants that are not easily degraded by nature and for that reason become persistent. Soil samples from ...

Alkyd resin was prepared from Hura crepitans (sand box) seed oil and Luffa cylindrica (sponge gourd) seed oil. The oil was extracted from the seed. Physicochemical properties and hydrolysis of the oil were carried out ...

Chitosan was derived from crab shells through deacetylation process using 50% NaOH. The obtained chitosan was used for adsorption studies. Adsorption parameters such as pH, contact time, metal concentration, adsorbent ...

Extraction of amorphous silica from corn cob ash (CCA) was carried out by sol-gel method. Silica xerogel was produced by dissolving CCA with alkali solution to form sodium silicate solution. The pH was lowered to7.0 ...

Leucaena leucocephala biomass was modified using sodium hydroxide and Fenton’s reagent and their effectiveness for the removal of metal from aqueous solution was investigated under various experimental conditions such as ...

This study investigated the levels of heavy metals in 22 foodstuffs obtained from each of 3 different localities (Akure, Ilara-Mokin, and Ogbese) in Ondo State. The foodstuffs examined cut across the classes of foods such ...

Oil was extracted from Pterocarpus erinaceus dye with hexane using a soxhlet. The percentage oil content was found to be 5.1 %. Some physicochemical parameters of the oil were then determined. Iodine value, Saponification ...
