Photocatalytic Degradation of Microplastics: Parameters Affecting Degradation

Advances in Environmental and Engineering Research, 2023
Recently, microplastics have emerged as a major environmental pollutant and have been documented globally. Several studies have shown that microplastics can accumulate heavy metals and persistent organic pollutants as they pass through the environment due to their functional groups interacting with and complex these substances.
