Polyacrylamide (PAM) is a synthetic polymer obtained by polymerization of acrylamide monomer, with the molecular formula CH 2 CHCONH 2. It is majorly used for flocculation of solids in a liquid, in processes such as water treatment, paper
Acrylamide and Polyacrylamide: A Review of Production, Use, Environmental Fate and Neurotoxicity, Reviews on Environmental Health | 10.1515/REVEH
PRODUCTION, USE, AND DISPOSAL Acrylamide was first produced in 1893 by Moureu in Germany. In 1952, Hercules started making research quantities and by 1954 began commercial production /14, 15/. The production of acrylamide in the USA was 39.1
Anionic Polyacrylamide for the Coal Washing Flotation Reagent T he Anionic Polyacrylamide is usually used in the processing of the coal washing. The coal washing processing can create a large amount of waste water, the impurities in the waste

How to select appropriate polyacrylamide for chemical waste water treatment
Generally speaking, we will use anionic polyacrylamide to capture the inorganic particles in inorganic chemical water treatment plant and use cationic polyacrylamide to capture the organic particles.
Poly(acrylamides) (PAMs) with various anionic and cationic charge densities from −1.64 to +0.98 meq/g but similar molecular weights were synthesized through radical polymerization. One of the aqueous PAM solutions and an aqueous dispersion of

In this study, we assessed the effects of anionic polyacrylamide (PAM), synthesized biopolymer (BP), and biochar (BC) on the decomposition of 14 C-labeled maize residue in sandy and sandy loam soils. Specifically, PAM and BP with or without 14
- What is the refractive index of Pam solution?
- The refractive index of PAM solution increases with the increase of temperature, and the values of refractive index of PAM solution are in the range of 1.32–1.38. 1. Introduction
- Can nonionic polyacrylamide be used as a gel fracturing fluid?
- Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
- What is the optical properties of polyacrylamide (PAM) solution?
- The optical properties of polyacrylamide (PAM) solution play an important role in measuring PAM concentration of the solution in the polymer flooding of oilfield based on optical methods. Transmittance cm −1 °C by an infrared spectrometer) relation.
- What are the refractive index increments of polyacrylamide?
- The refractive index increments of polyacrylamide for various wavelength were determined both in the usual solvents (water, ethylene glycol, formamide) and in those so far unused (ethanolamine, dimethyl sulfoxide). The values thus obtained are compared with the reported data. The necessity to employ anhydrous polyacrylamide samples is stressed.
