In a test of the geochemical speciation portion of the effort, MINTEQA2 model ...
(´) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover procedures for the chemical,mass spectrometric, and spectrochemical analysis of nuclear-grade boron carbide powder and pellets to determine compli-ance with specif i cations.1.2 The values...
As, Cd, Co, Cu, Fe, and Ni have a high affinity for F5, indicating geogenic source, while Mn, Pb, Sn, and Zn have a high affinity for F3, indicating anthropogenic source. Fe–Mn oxide partition was dominant for nearly all PTEs due to elevated sorption of cations onto Fe–Mn oxides...
Consumer demand for fresh and functional horticultural products is on the rise.Perilla frutescens, L. Britt (Lamiaceae) is a potential specialty/niche crop for consumption and therapeutic uses with high contents of phenolic and volatile compounds. Plant growth, mineral composition, polyphenol profile an...
For a binary electrolyte as the solute, Y2 = Cv+z+ Av−z−(z+, valent cation: z−, valent anion), for example, Na2SO4 (where z+ = 2, z− = −1, v+ = 2, v− = 1), the chemical potential μ2(p,T) consists of the chemical potentials of cations and anions,μ...
Replacing a small fraction of cations in a host metal oxide with a different cation (also known as doping) provides a useful strategy for improving the catalytic activity. Here, we report transition metal (Fe, Co, Ni, and Cu)-doped α-MnO2nanowires synthesized by a one-step hydrothermal met...
A novel copper-bridged fluorescence turn-on sensing platform for high-performance recognition, cell-imaging and paper test of CO is reported.

Cations were separated on a SUPP C4 cation column using a mixture of HNO3/(COOH)2 2.00 mM. Anions were separated on a SUPP 5 anion column, preceded by a guard column of the same material, using a solution of Na2CO3/NaHCO3 3.20 mM; flow cell 1.00 mL∙min−1 and 0.7 µS ...
In chemical reactions, they tend to form positive ions (cations) as they lose negative electrons. Physically, metals tend to be shiny and malleable, and they are good conductors of heat and electricity. This large category of elements includes some of the most famous elements of all time. ...
Main function :Widely used in the analysis and methodological studies of anions, cations, organic acids, organic amines, cyanide, sulfur ions, iodide ions, sugars and amino acids in samples from industries such as environment, materials, chemicals, food, biology, and medicine . Triple quadrupole ...
