sodium hypochloritesmear layerIntroduction. Canal irrigation is an important segment of endodontic treatment. The aim of this study was to assess the efficacy of 0.5% NaOCl solutions of different pH values on smear layer removal. Material and Methods. Thirty-two freshly extracted single rooted teeth...
The Transmissive pH Probe’s form factor provides very fast response with high signal strength, though is limited to clear, non-turbid solutions. These sensors are compatible with aqueous solutions, ethanol/methanol solutions, ammonia, peroxides, and sodium hypochlorite solutions.Transmissive Probes and ...

(b1,b2) a 10-cm long silver wire was immersed in a commercial bleach or sodium hypochlorite (NaClO) solution for 5 or 10 min, rinsed rigorously with DI water, and dried at RT, and (c1–c5) a 10-cm long silver wire was first chlorinated in a commercial bleach solution of NaClO for...
There are two main ways to lower the pH level in a pool. The two chemicals used to dose swimming pools and decrease pH are sodium bisulfate and muriatic acid.
The inactivation of Vibrio parahaemolyticus cells that were unattached or attached to a polyethylene terephthalate (PET) disc in pH-controlled sodium hypochlorite (NaOCl) solutions was studied under turbulent conditions. No significant desorption of attached cells occurred at the free available chlorine (...
The organic N-chloramines were prepared by combining sodium hypochlorite with each amino acid or peptide (glycine, Ala-Ala and Arg-Gly-Asp-Ser), at a N:Cl molar ratio of 1:0.4, and then used to treat E. coli suspensions for 180 min. No evidence of inactivation was observed at pH 8.1...
