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 least-squares methods to R 6·9%. The unit-cell ...
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...
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) (...
Preferred Group 1 metal/silica gel compositions of the invention are those containing sodium, potassium, or sodium-potassium alloys with sodium and sodium-potassium alloys being most preferred. Each stage of the Group 1 metal/silica gel composition of the invention may be used as a reducing agent...
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 ...

The hydroxyl functional groups (shown in Table 6.2) that exist in water consist of a hydrogen atom and an oxygen atom bonded together. It is the dominant reactive surface functional group for clay minerals, amorphous silicate minerals, metal oxides, oxyhydroxides, and hydroxides (Sposito, 1989)...
