Deliquescence and efflorescence are the two most important physicochemical processes of aerosol particles. In deliquescence cycles particles, many fundamental problems need to be investigated in detail on molecular level, including ion molecule interactions supersaturated aerosols, metastable solid phases that may formed, microscopic structures mechanisms This paper presents a summary progress made recent investigations particles by four common spectral techniques, which known as...
Quality silicate fertilizers should be in great demand, and yet the production has been limited due to heavy metals slags. In chemical deashing of coals for ultraclean coals, silica gels high purity were precipitated separated from acid solutions, which could used produce quality by pulping with CaO or MgO under mild conditions. By varying Ca/Si molar ratios, different compositions prepared, active contents measured validated ICP colorimetric methods. For curve versus four regions clearly...
Coal ashes (minerals) could be chemically removed to produce ultraclean coals for advanced utilizations such as oil substitutes and electrode materials. To eliminate secondary pollution reduce deashing cost, chemicals should recycled valuable byproducts developed, in addition coals. In this work, an alkali–acid (NaOH–HCl) chemical method featuring submolten salts was used deash with high ash of 27.95%, were prepared low 0.62%. The alkali solutions after treating regenerated by adding CaO,...
In recent years, one type of alumina rich fly ash (ARFA) with about 50 wt% has been extensively investigated for extraction in China. Due to the silica ARFA, would have generate a huge amount solid waste. There is growing interest glasses because they are composed mainly and could be removed prior extraction. this work, ARFA by chemical methods, that is, acid base digestions. The compositions measured XRF from digestion processes. K 2 O standard, XRD, FTIR spectroscopies were successfully...
