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 ...

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Assessing Soil and Management Quality Indexes in A Rural Watershed Under Long‐Term No‐Tillage in Southern Brazil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil quality assessment is essential to detect management failures and prevent land degradation in agricultural systems. No‐tillage system (NTS) is a conservation management widely adopted in Brazil, but its effectiveness is compromised when adherence to the core principles of crop rotation and ground cover is not complete, and basic ...
