This study aims to treat heavy metal pollutants in water by applying red mud particle waste. An experiment on the static adsorption of ions Pb2+ (or Cd2+ and Cu2+) particles was carried out, influences type ion, ion concentration, pH value, dosage, reaction time, temperature performance were explored. The competitive mechanisms various coexisting compared. samples loaded not with detected zeta potential measurement, scanning electron microscopy, Fourier transform infrared spectrometry....
The adsorption capacity of oyster shell powders (SPs) and the mechanism heavy metal ions (HMs; i.e., cadmium Cd 2+ lead Pb ) on SPs are discussed by means kinetics tests, adsorption-desorption scanning electron microscopy Fourier transform infrared spectroscopy. influences seepage velocity, types, SP addition amount/concentration effect in treatment HMs laterite as well quartz sand were analyzed. Studies have shown that i) can be divided into three stages, surface stage, internal pore...
ABSTRACT A theoretical model of the migration process high‐alkalinity red mud particles in porous media was derived from granular thermodynamics, complying with complementary motion two‐phase flows (i.e., hydroxide ions and powder). From perspective energy dissipation provoked by particle molecular thermal motion, a suspended under mixed conditions established. This naturally considers complex adsorption/desorption between (or particles) medium solid matrix, as well particles. Moreover,...
Over the vast Northwest China, arid desert contains high concentrations of sulfate, chloride, and other chemicals in ground water, which poses serious challenges to infrastructure construction that routinely utilizes portland cement concrete. Rapid industrialization region has been generating huge amounts mineral admixtures, such as fly ash slags from energy metallurgical industries. These industrial by-products would turn into waste materials if not utilized time. The present study...
The main purpose of this study was to characterize the mineral and chemical composition typical red muds in China. Changes physicochemical microstructural properties collected from Shanxi Shandong provinces were investigated after they immersed an alkaline NaOH or acidic HCl solution for 7, 28, 120 days. results showed that mud has a high cation exchange capacity active properties, which can be closely related its extremely alkalinity complex microstructure. neutralization with release Na+...
The combined action of sulfate and chlorine salts erodes concrete structures in coastal saline-alkali zones. induced fractures under load also accelerate the deterioration concrete. In this study, ion erosion tests fractured coal-gasified ash slag (FC-GAS) dry-wet cyclic conditions were performed using ordinary as reference. mass loss rates, relative dynamic moduli elasticity, distribution patterns ions specimens erosive environments single salt, mixed measured. mechanism FC-GAS coupled by...
This paper presents experimental investigations on the joints of concrete frame beams and columns with 20% coal ash slag replacing cement. The failure mechanism as a cement replacement is examined, focusing impacts two scenarios—concrete ordinary concrete—on mode seismic performance beam-column joints, well influence varying strength grade when content 20%. main research variables are presence in grade. Findings reveal typical modes at beam-end flexural plastic hinge, progressing through...
