Efficient Removal of Deltamethrin from Aqueous Solutions Using a Novel Lanthanum Metal–Organic Framework: Adsorption Models and Optimization via Box–Behnken Design

Abstract

Eliminating pesticides is essential for lowering the dangers to our environment. To do this effectively, it is crucial to find adsorbents with remarkable adsorption capacities, easy retrieval, and separation. Metal−organic frameworks (MOFs) have been extensively recognized for their exceptional ability to absorb pollutants. Therefore, we used novel lanthanum metal− organic frameworks (La-MOFs) to eliminate deltamethrin (DEL) from aqueous solutions. We proved through experimentation that the La-MOF is an efficient adsorbent for DEL from water. A study of the material revealed that the adsorbent had a surface area of 952.96 m 2 per gram and a pore volume of 1.038 cm 3 /g. These outcomes show how this substance can absorb particles. Utilizing kinetic models and conforming to the pseudo-second-order model, a thorough analysis of the efficiency of DEL adsorption onto La-MOF was conducted. To create a perfectly tailored approach, we utilized many parameters. The synthetic La-MOF adsorbent may undergo up to five steps of adsorption−desorption and has exceptional cyclability and reusability. To confirm purifying wastewater samples in the laboratory, the presentation of the established adsorbent was evaluated. For the management of industrial effluent and water filtration, the La-MOF adsorbent offered a simple and effective solution. Our investigation suggests that the method we describe for removing DEL from wastewater samples using the La-MOF adsorbent is unique.
