Extraction of silica gel from Sorghum bicolour (L.) moench bagasse ash

Sweet sorghum (Sorghum bicolor (L.) moench), a crop that is grown by subsistence farmers in Zimbabwe was used to extract silica gel in order to assess its possible use as a raw material for the production of silica-based products. The gel was prepared from sodium silicate extracted from sweet sorghum bagasse ash by sodium hydroxide leaching. Results show that maximum yield can be obtained at pH 5 and with 3 M sodium...

Multifactorial discriminant analysis of leaf oil of C. odorata L. King and Robinson from Côte d'Ivoire

The chemical composition of 71 essential-oil samples isolated from the leaves of Chromolaena odorata harvested in eight Ivoirian sites (Toumodi, Dougba, Yamoussoukro, Zambakro, Toumbokro, Attiegbakro, Tiebissou and Tie-N’Diekro) was investigated by GC-FID, including the determination of retention indices (RIs), and by 13C-NMR analyses. In total, 31 components accounting for 55.5 - 90.2% of the oil composition were...

A physico-chemical analysis of soil and selected fruits in one rehabilitated mined out site in the Sierra Rutile environs for the presence of heavy metals: Lead, Copper, Zinc, Chromium and Arsenic

The accumulation of heavy metals in soils especially in mining environments is of increasing concern to researchers in the Agricultural Industry. This is because the metals are biomagnified by plants. Accumulation of heavy and trace metals in plants occur by various sources but soil is considered the major one. Consumption of vegetables and fruits containing heavy metals is one of the main ways in which these elements...
