A previous study in female dugongs ana- lyzed elements in the 55 annual incremental longitudinal sections of tusks, and reported the presence of nine elements: barium (Ba), lithium (Li), sodium (Na), calcium (Ca), iron (Fe), magnesium (Mg), phosphorus (P), strontium (Sr) and zinc ...
In subject area:Chemistry Elemental Magnesium is a lightweight alkaline metal with atomic number 12, known for its high strength, exceptional vibration damping characteristics, and ease of fabrication. It is commonly used in the production of magnesium alloys for various applications due to its unique...
In this work, a method employing coprecipitation procedure with magnesium hydroxide as a carrier for separation/preconcentration of arsenic(V), cadmium(II), chromium(III), cobalt(II), copper(II), manganese(VII), mercury(II), nickel(II), and vanadium(V) was developed. The method was applied...
Beryllium is soluble in hot nitric acid, diluted hydrochloric and sulfuric acids and sodium hydroxide. It is like aluminum and magnesium in many ways. It resembles the two chemically and it readily creates compounds with other elements. Beryllium can’t be found in nature. This chemical is resis...
In this study, trace elemental signatures (TES) of the goose barnacle Pollicipes pollicipes, collected from ten sites along the Portuguese coast, were employed to discriminate individual's origin. Barium (Ba), boron (B), cadmium (Cd), chromium (Cr), lithium (Li), magnesium (Mg), manganese...
it is intended to include the bisulfite salts of the relatively stronger bases. Especially suitable alkali metal sulfite compounds are sodium sulfite and potassium sulfite. Likewise, suitable alkaline earth sulfites are exemplified by magnesium sulfite. The preferred sulfite compounds for purposes of the...
The detailed procedure was described as the following [37]: 1.66 g of sodium metaaluminate and 0.41 g of potassium hydroxide were dissolved in 126 mL deionized water. Then, 16 mL of HMI was added to the mixture, added dropwise and stirred. Into a homogeneous mixture, Characterization of as...
Potassium, magnesium, and phosphorus limitation is known to occur in natural groundwater, and the release of these elements may result in a significant increase in the rates of microbial processes. Importantly, samples B-1, B-4, and K-2 contained the highest amount of available iron, while ...
