Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...
