Multiwalled Carbon Nanotube (MWCNT) reinforced silica aerogel was synthesized in a very simple and cost effective sol - gel method. The process was followed by ambient pressure drying, and then the aerogel material was characterized by XRD, BET, SEM, EDX and FT-IR. 2.3 x 10-3 wt% MWCNTs were successfully incorporated in sodium silicate based silica aerogel. This metal-free nanocomposite catalyz...
We evaluated the use of ion-exclusion chromatographic systems for analyzing the behavior of inorganic ions (e.g., bicarbonate, sulfate, chloride, nitrate, phosphate, dissolved silicate, sodium, ammonium, potassium, magnesium, and calcium ions) in a suburban river located in Jakarta, Indonesia. Carbonate, phosphate, and silicate ion concentrations were determined using ion-exclusion chromatograp...
In this study, amorphous magnesium silicates with different SiO2:MgO molar ratios were synthesized by a precipitation reaction from sulfate (MgSO4), sodium silicate (Na2SiO3) and water. At laboratory scale, it was studied the effect of SiO2:Na2O ratio Na2SiO3 solution used as reagent on properties obtained. It observed that is key parameter in synthesis process these materials. The chemical com...
Purpose. To establish regularities of changes in sand-sodium-silicate mixtures (SSSM) relative water resistance, structured by steam-microwave solidification method (SMS), on their structuring parameters and sodium silicate solute (SSS) dissolution conditions. Methodology. Technical purity water, SSS with 2.83.0 modulus, quartz sand 0.23 mm average particle size were used this work. Studies car...
