Finally, the adsorption properties of D/P/Z on anionic pollutants such as methyl orange dye (MO) and nano polystyrene (NPS) plastics were investigated. The results showed that under favorable conditions, the adsorption rates of MO and NPS by D/P/Z4 reached 98.82 % and 91.53 % respectively within 5 min. Meanwhile, D/P/Z4 exhibited excellent recyclability, maintaining an adsorption rate of MO higher than 50 % even after 10 cycles. Electrostatic interaction was the key factor contributing to the high adsorption capacity of D/P/Z4. Moreover, the incorporation of polydopamine not only enhanced the stability and uniformity of ZIF-8 loading on the diatomite surface but also further improved the adsorption capacity of the adsorbent.
