Impact of Land use on soil quality: Insights from the forest-savannah transition zone of Ghana

Heliyon
Land use changes have a profound impact on soil fertility and agricultural production systems in the Forest-Savannah Transition Zone (FSTZ) of Ghana. Soil erosion and shortened fallow periods exacerbate soil fertility loss, further degrading soil quality.

Degradation of Reactive Red 180 and Safranin and a Comparative Analysis of Photocatalysis and Photo‐Membrane Systems for Real Textile Wastewater Treatment

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study examined the degradation of Reactive Red 180 and safranin using zinc oxide photocatalysis. Complete dye removal was achieved for both dyes under optimal conditions within 2 h. For Reactive Red 180, the optimum conditions were pH 10, 0.5 g/L zinc oxide, 25 ppm dye concentration, and 1 L volume. For safranin, the conditions were pH 10,
