Development of urea formaldehyde and polystyrene waste as copolymer binder for emulsion paint formulation

Urea formaldehyde, that is, trimethylol urea (TMU) resin was synthesized and blended with polystyrene waste (PS) to develop TMU/PS copolymer binder for emulsion paint formulation. The resulting copolymer was analysed for formaldehyde emission and other physical properties such as viscosity, gel time, density, turbidity, refractive index, melting point and moisture uptake, elongation at break and solubility in water....

Characterization of chrome buffing dust (CBD) generated from NILEST tannery associated with pathogenic fungi

An attempt was made to monitor the level of chromium from chrome buffing dust waste (CBD) from Nilest tannery through preliminary investigation of the physicochemical characteristic of dried buffing dust (CBD) waste: pH, temperature (°C), alkalinity (mg/L), ash content (%), crude fibre (%) for example, using effluent and reference water sample as (control). Comparative study of the mean values of CBD, effluent and...
