摘要:

Phenols of natural and antropogenic derivations are respected to the dangerous and wide occurring organical impurities coining in the environment with waste waters of chemical plants. Maximum permissible concentration (MPC) of phenol for unchlorinated water is 0.1 mg/l, and for chlorinated one - 0.001-0.002 mg/l. For the determination of such small contents of phenol in waters preliminary extractional or sorptional concentration is used.
