Abstract Results obtained by microwave
(MW) and simultaneous microwave and electron beam (MW+EB) application in the
chemistry of acrylamide and acrylic acid
co-polymers (PA type polyelectrolytes) are
presented. Comparative results concerning the molecular weight (Mw)
and Huggins' constant for the acrylamide copolymers
obtained by classical heating, MW heating, EB irradiation and simultaneous
MW+EB treatment are reported. MW heating produces high PA water solubility
but median Mw values; EB irradiation gives high Mw
values but associated with a cross-linked structure (poor water solubility)
while MW energy addition to EB energy gives simultaneously high Mw
values and high PA water solubility. AMW installation of 2.45 GHz and 2.S kW,
designed to provide small-scale commercial production of PA polyelectrolytes, is described. Key Words: Microwave heating, electron beam irradiation, simultaneous treatment, polyelectrolytes, wastewater treatment |
