Although homogeneity at the atomic level of CeO2-ZrO2 with a Ce/Zr atomic ratio close to unity is considered to be one of the main causes for the increased total oxygen storage capacity (OSC), the characterization approaches of homogeneity remain a major challenge. We propose a simple, yet effective method, to assess both structural and compositional homogeneity of CeO2-ZrO2 by using Eu(3+) lum...

Methyl parathion (MP) is a very toxic organophosphate pesticide used as a non-systematic insecticide and acaricide on many corps. As MP and its by-products are highly toxic, they have to be retained to avoid pollution of rivers and lakes. Highly efficient sorbents are hydrotalcites (HTs) (or anionic clays). We have correlated the degradation of an aqueous solution of MP at room temperature, wit...

Approximately 10 % of CO2 is emitted from an ordinary Portland cement production. In and concrete production, emissions can be greatly reduced by using Supplementary Cementitious Materials (SCMs). addition, the microstructure durability properties are improved when silica-rich SCMs used. this study, Eco-Friendly design was carried out three different SCMs. Diatomite, ground granulated blast fur...

Nitrated phenols from residential combustion aggravate the greenhouse effect and endanger human health. To search for an ideal fuel which produces low nitrated phenols, high-sodium coal, conventionally used in coal-fired power plants, has been considering that construction of civil stoves makes it easy to deal with slag fouling. In this study, we investigated pollutant emissions by comparing th...

In this research, the adsorption rates of cyanide and palladium onto Fe3O4/alginate/diatomite nano-adsorbent (FADA) were evaluated. The co-precipitation technique was applied to synthesis FADA. response surface methodology (RSM) employed investigate relation between input-independent factors (initial pollutant concentration, contact time, FADA dosage pH) one dependent output (removal efficiency...

A cordierite powder was synthesized from a batch composition of talc, diatomite and alumina. Sintered samples of the synthesized cordierite were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA), and Rietveld analysis. The XRD analysis showed hexagonal or a-cordierite (indialite) as a major phase along with MgAl2O4 spinel and cristobalite as secondary phases in the s...
