Question

Given the Kow xylene ( any isomer) and Henry's law constant (KH) which method would you use to clean up groundwater contaminated with w/xylenes. justify answer.

Answer 1

1) i would go for Henry's law constant (KH) method because

A measure of a contaminant's tendency to partition between the aqueous phase and gaseous phase. The higher the Henry's law constant, the greater the tendency to volatilize from the dissolved phase and more easy to clean up the ground water contamination .

while   Kow xylene ( any isomer) comes under Effective Solubility

The greater the contaminant's solubility, the greater the dispersion in groundwater ( more soluble in ground water )

more difficult to seperate it . However, in a mixture, the solubility of each component is reduced–effective solubility is less than pure phase solubility
