To absorb or be absorbed through a chemical process rather than purely physical means, involving chemical bonding or reaction.
From chemo- (chemistry) + sorb (from Latin sorbere, 'to absorb'). This verb combines chemical principles with absorption, describing a more active form of uptake than simple physical absorption.
