Abstract:

As an antibacterial agent, triclosan (TCS) has been widely used in medicine and personal care products, and has become a ubiquitous pollutant in the water environment. Because it has biological accumulation, endocrine interference effect, reproductive toxicity and other hazards, and has been proved to be the precursor of some more toxic substances, the harmless treatment of TCS in water has attracted wide attention. The adsorption treatment method has the advantages of simplicity, green and high efficiency. The adsorption effects of different types of adsorbents on TCS were summarized, the possible effects of some parameters of water on the adsorption process were analyzed, and the kinetics and thermodynamics of the adsorption process were discussed. Finally, the research direction of TCS adsorption treatment was prospected. In general, the development and application of green, low-cost and renewable adsorbents is an important research direction. The modification and compounding of adsorbents are effective ways to improve the adsorption effect. In order to better apply to the treatment of TCS in the actual environment, the adsorption mechanism of TCS and the influence mechanism of environmental factors need to be further studied.

Key words: triclosan, adsorbents, adsorption mechanism, influencing factors
