Purification of Chloride Melts for Electrochemical Experiments

Check if the same lab product or an alternative is used in the 5 most similar protocols

The analytical grade chemicals, LiCl (Xilong Chemical Co., Ltd), KCl (Xilong Chemical Co., Ltd), YCl₃ (99.9%, high Purity Chemical Co., Ltd) and PbCl₂ (99.9%, Aladdin Industrial Corporation) were applied in this experiment. The anhydrous LiCl–KCl eutectic melts with a 45.8 : 54.2 mass ratio was located in an alumina crucible as a supporting electrolyte. Then, the melts was dehydrated by heating at 473 K more than 48 h for the sake of removing extra water. And the other impurities in chlorides solvent were eliminated by pre-electrolysis at −2.2 V (vs. Ag/Ag⁺) for 4 h on a W electrode before the experiments. The PbCl₂ and YCl₃ power were led in the melts directly as Pb(ii) and Y(iii) resources, respectively.

The simulated gastric fluid (SGF)-resistance of S. Typhimurium was determined by subjecting the bacteria to SGF (pH 2.0 or 3.0) [15 (link)]. SGF consisted of 8.3 g/L proteose peptone, 0.6 g/L KH₂PO₄ (Xilong Scientific Co., Ltd.), 2.05 g/L NaCl, 0.37 g/L KCl (Xilong Scientific Co., Ltd.), 0.11 g/L CaCl₂ (Xilong Scientific Co., Ltd.), 0.05 g/L oxgall (Sigma Aldrich, St. Louis, MO, USA), 1 g/L lysozyme (Solarbio, Beijing, China), and 13.3/L mg pepsin (1:3000; Solarbio, Beijing, China). Except for the oxgall, lysozyme and pepsin (sterilized by 0.25-μm filters), all the components were dissolved in deionized water and autoclaved. The solution was adjusted to pH 2 or 3, respectively, with 6.0 M HCl. Homogenized beef samples from the 405-nm LED illuminated and non-illuminated groups were transferred into SGF at a ratio of 1:9 (homogenized sample: SGF solution) and incubated with shaking (130 rpm) at 37 °C. At sampling times, each sample was serially diluted in PBS and plated on XLD-agar at 37 °C for 24 h for colony enumeration.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
