Sodium carbonate (commonly called as soda ash or washing soda) is the primary product of the chemical industry since the year one. It was used in antiquity for the manufacture of soap and glass, using the mineral appears in some lakes of Africa, Asia and North America being a natural soda, so-called trona (Na2CO3·NaHCO3·2H2O). In Europe, the most important was the soda ash produced in Spain, No...
One hundred and forty-one glass fragments from medieval Ciudad de Vascos (Toledo, Spain) were analysed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The glasses fall into three types according to the fluxing agents used: mineral natron, soda-rich plant ash, and a combination of soda ash and lead. The natron glasses can be assigned to various established primary pro...
Use of ethnoveterinary remedies in the management of foot and mouth disease lesions in a diary herd.
An outbreak of Foot and Mouth Disease (FMD) affecting 95 (57.2%) out of 166 cattle occurred in a medium-scale dairy farm in Kikuyu district, Kenya. Ethnoveterinary remedies of natural Soda ash solution (97% sodium bicarbonate), honey and finger millet flour were used to manage the FMD lesions. The lesions were washed with soda ash solution to remove the necrotic tissue after which raw honey and...
In the present study, a hydro-refining spent catalyst with an alumina base has been taken into consideration. It is mostly used for the recovery of molybdenum. The spent catalyst constitutes around 21 pct of molybdenum as molybdenum oxide. The study has revealed that at temperature lower than 600C, it is possible to recover an appreciable quantity of molybdenum from the spent catalyst. The stat...
in this study, the main papermaking characteristics of soybean straw (glycine max) as an agricultural residue were investigated. the fiber biometry and chemical composition of soybean straw were determined. the properties of pulps from soda, soda-aq and monoethanolamine (mea) processes were compared. the average fiber length, fiber diameter, lumen diameter, and cell wall thickness were found to...
Contamination types, levels and their behavior within drilling wastes is determined by the local geological conditions and drilling mud design; notably lubrication fluids, weighting agents and anti-foaming agents. Such additives can contain potentially toxic elements such as aluminum and barium. Besides being contaminated, drilling wastes often have a high pH due to the addition of lime, causti...
Novel low-temperature process that, with the availability of green electricity, enables production carbon-neutral cement, lime, and soda ash.
