Synthesis of Hydrophobic Cationic Polymeric Flocculants
Cationic polymeric flocculants are used as chemical regulators because of their excellent performance and economic advantages. Current research focused on synthesizing flocculants Polyacrylamide, methacrylamido propyl trimethyl ammonium chloride, Lauryl acrylate, and Poly Acrylamide, methacrylamido propyl trimethyl ammonium chloride (PAT).
Fig. 1 shows the infrared spectroscopy of starch and the STC-g-PDMC.Three new adsorption peaks, at 1729, 1480 and 953 cm −1, were observed in the spectrum of the STC-g-PDMC compared with starch.The new peak at 1729 cm −1, came from the vibrating adsorption of carbonyl groups in the grafting PDMC.The other two peaks at 1480 cm −1 and 953 cm −1 could be assigned to the methyl groups of

- What is polyacrylamide gel electrophoresis (PAGE)?
- As a well-established electrophoresis technique, polyacrylamide gel electrophoresis (PAGE) is ubiquitously applied to routine protein analyses in biochemistry and molecular biology labs [ , , ].
- Are polyacrylamide gels better than agarose gels?
- Polyacrylamide gels have the following three major advantages over agarose gels: (1) Their resolving power is so great that they can separate molecules of DNA whose lengths differ by as little as 0.1% (i.e., 1 bp in 1000 bp). (2) They can accommodate much larger quantities of DNA than agarose gels.
- How much DNA can be applied to a polyacrylamide gel?
- Up to 10 µg of DNA can be applied to a single slot (1 cm × 1 mm) of a typical polyacrylamide gel without significant loss of resolution. (3) DNA recovered from polyacrylamide gels is extremely pure and can be used for the most demanding purposes (e.g., microinjection of mouse embryos).
- What is discontinuous polyacrylamide gel electrophoresis?
- In its original version of discontinuous polyacrylamide gel electrophoresis (Davis, 1964 ), a strategic use of different buffer systems in the gel, in the sample, and in running buffer caused the proteins in the sample to focus into a sharp band before entering the gel.
