Photoadsorption and reaction mechanism of periwinkle shell ash in the removal of hazardous dye

Water Practice and Technology, 2023
AbstractCombined adsorption and photocatalysis synergy was explored in this research because the porosity of activated carbon and hydroxyl radicals' generation are the main drivers of the adsorption and photodecomposition efficiency of dyes. In this study, periwinkle shell ash (PSA) activated at 800 °C was used for the adsorption of toxic crystal ...

Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

Engineering Reports, Volume 5, Issue 1, January 2023., 2023
Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

Potential Heterogeneous Catalysts from Three Biogenic Residues toward Sustainable Biodiesel Production: Synthesis and Characterization

ChemistrySelect, Volume 7, Issue 48, December 27, 2022., 2022
Heterogeneous base catalysts were synthesized from the periwinkle shell, melon seed husk, and locust bean pod husk via thermal decomposition at 800°C. The catalysts were characterized by their elemental, structural, and functional compositions. The three catalysts gave appreciable biodiesel yields and good stability throughout the transesterification ...

Optimization on the Mechanical Properties of Aluminium 8079 Composite Materials Reinforced with PSA

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
AA 8079 with variable percentages of peanut shell ash (PSA) was created by stir casting (2.5 percent, 5 percent, 7.5 percent, 10 percent, 12.5 percent, and 15 percent). Compared some of the physical and mechanical properties of the composite material were to the alloy matrix alloy (density; porosity percentage; hardness; wear index; tensile strength ...

Swelling Potential of Clayey Soil Modified with Rice Husk Ash Activated by Calcination for Pavement Underlay by Plasticity Index Method (PIM)

Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021
Volume change in expansive soils is a problem encountered in earth work around the world. This is prominent with hydraulically bound structures or foundations subjected to prolonged moisture exposure. This behavior of clayey used as subgrade, foundation, landfill, or backfill materials causes undesirable structural functionality and failures.
