Role of water, acetic acid and chloride on corrosion and pitting behaviour of carbon steel in fuel-grade ethanol The role of water, acetic acid, chloride, and oxygen level in corrosion and pitting behaviour of carbon steel in simulated fuel-grade ethanol (SFGE) was in... Xiaoyuan,Lou,and,...
To relieve lactic acid inhibition, an aqueous two-phase system (ATPS) was used to grow Lactococcus lactis . Its composition was 11% (w/v) PEG 20000/3.5% (w... C Li,F Ouyang,J Bai - 《Biotechnology Letters》 被引量: 32发表: 2000年 加载更多来源...
The highest acid and base strengths of the SO42- compound were H0 ≤ 1.5 and H- ≥ 12.2, the acidity and basicity being 0.3 and 0.1 mmol/g, respectively.doi:10.1346/ccmn.1977.0250103Miyata, ShigeoGeoScienceWorldClays & Clay Minerals
For the equilibrium {eq}HSO_4^- + HPO_4^{2-} \to SO_4^{2-} + H_2PO_4^- {/eq}, what is a conjugated Bronsted-Lowry acid-base pair? Conjugated Bronsted-Lowry Acid-Base Pair: A conjugate base is a leftover after a Bronsted-Lowr...
Marek Marczewski37 reported a SO42−/Al2O3 system, where the acid strength of SO42−/Al2O3 catalyst could be tuned based on the concentration of H2SO4 solution through incipient wetness method. Therefore, we next optimized the condition of SO42−/Al2O3 catalysts for the acetalization...
However, research about the effects of acid radical ions impurities on the corrosion of materials in molten fluoride salt is very limited. In FLiNaK salt, three primary acid radical ions (sulfate (SO42−), phosphate (PO43−) and nitrate (NO3−)), can be mainly introduced from the ...

24. Or a retinol body lotion, because the magic of retinol is not just for your face! This retinol in the creamy formula helps promote skin cell turnover, while the ferulic acid firms skin for a tighter appearance. Reviewers also note that this works wonders on rough, bumpy skin on their...
Makeup Melting Cleansing Balm, which is an absolute *treasure* among reviewers with sensitive skin. This nourishing blend contains hyaluronic acid to hydrate skin and help protect your moisture barrier, gently cleansing your skin of potential irritants *and* helping prevent more from working their ...
using EDTA and salicylic acid as an indicator [5], The change of colour from dark violet to colourless or faint light yellow (depending on the amount of iron to be titrated) is very sharp. The concentration of the iron solution was 59-34 mg Fe 100 ml N/10 H2SO4 . (c) I o...
