Photocatalytic remediation of persistent organic pollutants (POPs): A review

© 2020 The Authors The release of persistent organic pollutants (POPs) into the environment is an issue of global concern, as the chemicals are stable over a prolonged period resulting in their accumulation in many animals and plants. Although POPs are banned in several countries, many chemicals hav...
