Alkali metalsWater diffusionChloride releaseThe water loss and chloride release from four different formulations of magnesium oxychloride cement have been studied. The formulations were all based on 25% m/m aqueous MgCl2 and the solutions employed to prepare cements consisted of either MgCl2:water or ...
generating either a net positively or negatively charged ion. This group can also participate in chemical reactions to link molecules together, forming chains of sugars or fatty acids. The addition of a hydroxyl group converts many organic compounds into alcohols, enhancing their solubility in water...
In my own research I have used Group I metals as tools to perform other chemistry. Once I was in need of absolutely dry alcohol, and the driest I could buy still contained minute traces of water. The only way to get rid of the last remnant of water was by treating the water-containin...
Any of a group of soft metals that form alkali solutions when they combine with water. They include lithium, sodium, potassium, rubidium, cesium, and francium. Except for cesium, which has a gold sheen, alkali metals are white. The alkali metals have one electron in their outer shell, and...
This allows thiols to form stable complexes with transition metals such as arsenic, copper, mercury and lead. This chemistry is the basis of metal chelation therapy for heavy metal toxicities such as the use of penicillamine for copper accumulation associated with Wilson's disease (Fig. 1) (...
Carbon compounds of the transition metals. Part XXVII. Crystal and molecular structure of [bis(biphenylylidene)butatriene]hexacarbonyldi-iron, a binuclear metal cumulene complex The crystal structure of the title complex has been determined from 1351 visually estimated X-ray intensities and refined by...
The process comprises the steps of: a) oxidizing the one or more Group VIB metals to one or more Group VIB metal oxides; b) separating the one or more Group VIB metal oxides from the one or more Group VIII metals; c) dissolving the one or more Group VIB metal oxides in water to ...
water contain at least 1 ng/L of PFOX (Ahrens 2014), and most treatment and toxicology research is based on these two compounds. However, fluorotelomers (FTs) and perfluoroalkylether acids (PFEAs) have replaced PFOS and PFOA, leading to new profiles of persistent PFAS in groundwater (Backe...
Water and sediment samples from seven water bodies along the coastal belt of Ghana were assessed for the deposition of platinum-group metals (PGM), i.e. platinum, palladium and rhodium. Source analysis of the results indicated probable anthropogenic origins which had a strong linkage to automobile...
