Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

Chemistry – A European Journal, EarlyView.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Study on iron anchoring methods for magnetic biochar: Characterization, functional mechanism, and RBBR dye removal

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetic biochar (MBC) is a novel bio‐metallic composite material with high potential in sustainable water cleaning. Iron anchoring is critical in forming iron‐based MBC and will fundamentally impact its characteristics and functionality in dye removal applications. However, the mechanism is not well‐revealed.

Adsorption of 5G blue reactive dye using passion fruit pomace: Kinetics, ANN modelling, and process optimization

The Canadian Journal of Chemical Engineering, EarlyView.
Combination of ANN modelling and process optimization to achieve the maximum % dye removal. Abstract The present work reports on the use of artificial neural networks to predict the adsorption of 5G blue reactive dye (5GBRD) on yellow passion fruit pomace in a fixed‐bed process and the % dye removal optimization.
