Temperature influence of nonionic polyethylene oxide and anionic polyacrylamide on flocculation and dewatering behavior of kaolinite dispersions
Nonionic polyethylene oxide (PEO) and anionic polyacrylamide (PAM) flocculation of kaolinite dispersions has been investigated at pH 7.5 in the temperature range 20-60 degrees C. The surface chemistry (zeta potential), particle interactions
The viscosity average molecular weights, M v of the polymers were estimated by the Mark–Houwink equation. The literature reported values for k=1.05×10 −4 dl g −1 and α=0.73 for the cationic, k=1.91×10 −4 dl g −1 and α=0.71 for the nonionic polya

flocs. Final sediment height tends to decrease with an increase in polyacrylamide concentration, indicating denser particle associations (face-to-face) and verified with scanning electron microscopy. Viscosity tends to increase as polyacrylamide
The viscosity of polyacrylamide solution is related to its molecular weight and preparation concentration. The dissolution of polyacrylamide: the flocculation function can only be fully exerted
Nonionic Surfactant and Temperature Effects on the Viscosity of Hydrophobically Modified Hydroxyethyl Cellulose Solutions | The Journal
Nonionic surfactant and temperature effects on the viscosity of hydrophobically modified hydroxyethyl cellulose (HMHEC) solutions are investigated experimentally. Weak shear thickening at intermediate shear rates takes place for HMHEC at

Increasing the viscosity of injected water by the addition of polymer improves the displacement efficiency during the water flooding process. In this study, a sulfonated polyacrylamide copolymer has been added to salt water. Several parameters,
- What is polyacrylamide gel electrophoresis?
- The most commonly used polyacrylamide gel electrophoresis for quantitative protein analysis is Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The polyacrylamide gel forms by polymerizing acrylamide and a crosslinking agent, i.e., N, N’-methylene-bis-acrylamide.
- What is the difference between agarose gel and polyacrylamide gel electrophoresis?
- In polyacrylamide gel electrophoresis, polyacrylamide gel separates macromolecules, i.e., proteins of size five kDa to 250 kDa. Similarly, it can also isolate DNA of 5- 500 bp size. In agarose gel electrophoresis, agarose gel separates DNA, RNA, and protein. It can isolate DNA about 50-20,000 bp in size.
- Why is polyacrylamide gel electrophoresis useful in HIV testing?
- PAGE is helpful to analyze the size and number of polypeptide subunits. It is useful in HIV tests to separate HIV protein. Polyacrylamide gel electrophoresis consists of the following benefits:
- What is blue native polyacrylamide gel electrophoresis?
- Blue-Native polyacrylamide gel electrophoresis (Blue Native PAGE) was originally introduced by Schagger and von Jagow as a technique for separating enzymatically active membrane protein complexes under mild condition .
