Copper ions play a vital role in a variety of fundamental physiological processes not only in human beings and plants, but also for extensive insects and microorganisms. In this paper, a novel water-soluble ruthenium(II) complex as a turn-on copper(II) ions luminescent sensor based on o-(phenylazo)aniline was designed and synthesized. The azo group would undergo a specific oxidative cyclization...

PURPOSE Skin exposure to soluble beryllium compounds causes systemic sensitization in humans. Penetration of poorly soluble particles through intact skin has been proposed as a mechanism for beryllium sensitization; however, this mechanism is controversial. The purpose of this study was to investigate the hypothesis that particulate beryllium compounds in contact with skin surface release ions ...

Chemical phosphorylation of hydrolysate resulting from hydrothermal carbonization chicken feather waste was performed to enhance the amino acids and reduce metal ions content. The aim this research is improve functional properties feathers without impairing nutritional availability thereof with cheapest chemical method by phosphorylation. Phosphorylated can function as animal feed fertilizer. o...

A particle-into-liquid sampler (PILS) was coupled with a total organic carbon analyzer (TOC) and two ion chromatographs (IC) to enable high time-resolution measurements of water-soluble ions and water-soluble organic carbon (WSOC) by a single sampling and analytical setup. The new high time-resolution measurement system, the PILS-TOC-IC, was able to provide essential chemical and physical infor...

We measured the number concentrations of cloud condensation nuclei (CCN) and the size distributions of CCN/CN (CN: condensation nuclei) ratios at supersaturations (SSs) of 0.097, 0.27, 0.58, and 0.97% at Jeju Island, Korea during March-April 2005. We made simultaneous measurements of aerosol inorganic ions, water-soluble organic carbon (WSOC), organic carbon (OC), and elemental carbon (EC) in P...

Soluble additives are widely used to control crystallization processes, modifying the morphologies, sizes, polymorphs, and physical properties of product crystals. Here, a simple versatile strategy is shown significantly enhance potency soluble additives, ranging from ions amino acids large dye molecules, enabling them be effective even at low concentrations. Addition small amounts miscible org...

This paper studies the concentration rules of different components exudate based on original soil column test by using coal mine pit drainage and tap water as filter fluid to simulate water-rock interaction in sewage irrigation, clear irrigation or precipitation filtration, results show that is mainly dissolved soluble salt, followed cation exchange adsorption. The carbonic balance movement occ...

Water-soluble inorganic ions (WSIIs) were measured online in Beijing during the heating season of 2021, which 2022 Olympic and Paralympic Winter Games hosted. The characteristics PM 2.5 water-soluble investigated general, as well clean period, polluted periods. It was found that most episodes occurred under conditions low wind speed, temperature inversion, high relative humidity. total mass con...
