of the supernatant was filtered through 0.45 µm PTFE syringe filters (Phenomenex, UK) and placed in an amber-colored vial (AIM, screw vial, SV-15A). Quantification of ascorbic acid was made by an external standard method using an L-ascorbic acid standard (Sigma A5960). Samples were separated on a Luna C18 column (250 mm × 4.60
Sep 01, 2020 · The solution was filtered through a 0.45 syringe filter and read on the high-performance liquid chromatography (HPLC) instrument (Thermo Scientific UltiMate 3000; Thermo Scientific Amino Gold column) with the RID detector. Fructose, glucose, sucrose, and maltose (Sigma-Aldrich) standards were used for the calibration curve.

Jun 26, 2014 · Before 0.2 and 0.22 micron filters became standard, it was thought that filters with an absolute rating of 0.45 micron were thought to be sufficient to strain out even the smallest bacteria. However, the discovery of Brevundimonas diminuta, showed that there were still bacteria capable of passing through a 0.45 micron filter in large quantities.
filtering the samples with a 0.45 µm syringe filter. Hydrogen peroxide concentration was measured because of its interference on COD analysis. Therefore, COD concentrations were corrected using Eq. (1) recommended by Kang [25]. COD H2O2 (mg/L) = 0,4706[H 2 O 2] - -4,06*10 5[H 2 O 2]2 1 Table 2. Experimental plan for Fenton oxidation Experiment
