A significant number of empirical studies have been carried
out which prove the principle of microwave assisted demulsification
of water-in-oil emulsions, and report the importance of
pH, temperature, water and electrolyte content. Fortuny et al.
and Lemos et al. [4,11] report a reduction in demulsification efficiency
with the addition of electrolytes, but their experiments
were carried out at constant temperature, which led to a reduction
in microwave power input with the addition of NaCl. On the
other hand, Xia et al. [7]
