Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Characterization and Modeling of Industrial Phosphoric Acids' Rheological Behavior: Impact of Magnesium Monoxide on Viscosity

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the rheological behavior of industrial phosphoric acids (H3PO4) produced at the JORF–LASFAR phosphoric plant in Morocco, with P2O5 concentrations of 18%, 29%, 42%, and 54%. Rheological measurements were performed using a rotary cylinder rheometer over a shear rate range of 1–1000 s−1.
