In this study, an improved UPLC-MS (Ultra-high performance liquid chromatography-tandem mass spectrometry) method for simultaneously quantifying twelve major components belonging to two chemical types was developed and validated, and was applied to quantitatively compare the quality of sulfur-fumigated Astragali Radix of different durations and of the fresh reference sample. The results

2018/9/12 · A PTFE membrane with small opening size (0.22 μm) was used for the investigation on the effect of pressure. All carbon dioxide, methane, nitrogen, oxygen and hydrogen with a purity of 99% or more were procured from Daehan Special Gas CO. Membrane cells
In this process, the active plasma firstly destroyed the C–F and C–C bonds of PTFE, generating peroxy radicals on the membrane surface. When immersing the treated substrate into an acrylic acid (AA) solution, the peroxy radicals initiate the in-situ polymerization of AA, which provides carboxyl groups (–COOH) as grafting sites to firmly adhere g-C 3 N 4 /TiO 2 through the stable covalent
In this study, the feasibility of the direct contact membrane distillation (DCMD) process to recover arsenic, uranium and fluoride contaminated saline ground waters was investigated. Two types of membranes (polypropylene, PP; and polytetrafluoroethylene, PTFE) were tested to compare the permeate production rates and contaminant removal efficiencies.

2015/1/1 · 7.1. Introduction Heterogeneous photocatalysis is an advanced oxidation process (AOP) based on the use of a semiconductor (the photocatalyst). It has been extensively studied for about four decades, when Fujishima and Honda (1972) discovered the photocatalytic splitting of water on TiO 2 electrodes. electrodes.
membrane, they did not wet the omniphobic membrane (Figure 2). The wetting of the PTFE membrane with mineral oil and ethanol is dynamic; the liquids initially beaded up upon contact with the membrane as drops with measurable contact angles but then
