"While the polymer with lower concentrations of the sulfonic
acid groups had no practical effect against human adenovirus, it could destroy 99.997 per cent of that virus at higher sulfonic
"When microbes come into contact with the polymer, water on the surface of the microbes interacts with the sulfonic
acid functional groups in the polymer - creating an acidic solution that quickly kills the bacteria," says Reza Ghiladi, an associate professor of chemistry at NC State and co-corresponding author of the paper.
groups in the surface of SPS microspheres coordinated with [Pr.sup.3+] ion.
* Calimulse[R] sulfonates and sulfonic
acids offer great consistency and predictable performance in a variety of emulsion polymerization applications.
These include doping with organic acids, such as dodecyl benzene sulfonic
acid (DBSA)  or camphor sulfonic
acid (CSA) .
Tetrabromophenol blue has three parts, which are sulfonic
acid, 1,2,3,4-tetrabromobenzene, and 2,6-dibromophenol.
As a first step, AGC started sales of new fluorinated sulfonic
acid ion exchange membranes 'FORBLUE S-series' on November 6.
general population (>95%) has detectable serum concentrations of several PFAS, including perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic
acid (PFHxS), and perfluorononanoic acid (PFNA) (CDC 2017).
EPA) issued the following drinking water lifetime health advisory values for two PFAS compounds: 70 ng/L (or parts per trillion) for both perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic
Xu, Hegenbarth, and Chen developed a functional TFE copolymer fine powder containing 0.001 to 10 mol% comonomers with acid groups such as carboxylic, sulfonic
, or phosphoric acids pendant to the polymer chain.
In acids Sulfuric acid, Sulfonic
acid and Hydrochloric acid are usually used as acid catalyst.
