Preparation and characterization of polyacrylamide
Polyacrylamide grafted onto KH-570 modified PA via solution polymerization can provide an adsorbent with enhanced and selective separation of mercury ions from aqueous solutions. The objective of this work was to obtain the optimum preparation conditions for mercury adsorption. Solution polymerization of AM was performed on KH-570 modified PA.
Experiment 2: Characterization of polyacrylamide (PAM) by viscometry and gel permeation chromatography (optional) Aim: (a) To determine the intrinsic viscosity and molecular weight of polyacrylamide (synthesized in experiment 1) using a Ubbelohde capillary viscometer.
Characterization of a Polyacrylamide Solution Used
Biopolymers are viewed as effective and eco-friendly agents in soil modification. This study focuses on the wettability analysis of polyacrylamide (PAM) solutions for soil remediation. The contact angle, surface tension, and viscosity of PAM solutions were experimentally evaluated in air- and decane-biopolymer solution systems.

Viscosity average molecular weight of polyacrylamide The viscosity average molecular weight of polyacrylamides was carried out by determining the intrinsic viscosities of the polyacrylamides using Ubbelohede viscometer, no. 4809 ASTM at 25 ± 0.1ºC. The polyacrylamide solutions were prepared in distilled water.
In this study, a new profile control and flooding agent “polyacrylamide nanomicrospheres” with particle size of 120–180 nm was prepared by inverse microemulsion polymerization. The viscoelasticity of polyacrylamide nanomicrospheres and the swelling property of polyacrylamide nanomicrospheres in aqueous solution were characterized.
