Levels of trace metals and essential minerals in selected fruit juice samples purchased from Minna were determined using atomic absorption spectrophotometer (AAS) and Flame photometer. From the obtained result, Cu, Fe, Mn, Na, and Zn were present in all the samples, while Cd, Pb, and Cr were not detectable in all the samples. Concentrations of K range(More)
During compounding processes, polymer latexes are mixed with various colloidal systems (in particular, PVOH) or surface-active agents to modify the flow behaviour in order to suit the manufacturing process. In this study, the flow behaviour of aqueous dispersed PVAc, NR and different mixed dispersions were investigated both in the absence and presence of(More)
The effect of acetic acid and citric acid modification of cassava starch on the biodegradability of their films reinforced with lignin and nanofiber was determined. Cassava starch was first modified with acetic anhydride and citric acid, characterized, filled with lignin and nanofiber to produce the films. Biodegradation studies were based on determinations(More)
