Abstract

The invention discloses a preparation process and application of rosin-based quaternary ammonium salt positive ion surface active agent modified zeolite and belongs to the technical field of purification and pollutant treatment of drinking water sources. The preparation process comprises the steps of firstly, screening, cleaning, drying, cooling and crushing natural zeolite, and reserving for usage after sieving; and using a rosin-based quaternary ammonium salt positive ion surface active agent of 10mmol / L-100mmol / L to modify the zeolite, so that the rosin-based quaternary ammonium salt positive ion surface active agent modified zeolite is produced. The surface active agent modified zeolite is applicable to removal of dissolved organic matters (humic acid) in drinking water, anionic dye (congo red) in printing and dyeing wastewater and heavy metal pollutants such as copper ions. The preparation process has the advantages that the process is simple in technology, high in utilization ratio, low in cost, wide in application range and simple to operate, modifying agents and matrixes are environment-friendly materials and the like.

Description

technical field [0001] The invention belongs to the technical field of drinking water source purification and pollutant treatment, and relates to an adsorbent, in particular to a preparation method and application of a rosin-based quaternary ammonium salt cationic surfactant-modified zeolite. Background technique [0002] In recent years, with the rapid development of my country's social economy, the discharge of water pollutants has increased year by year, and the problem of micro-pollution in the water environment has become increasingly prominent. Natural organic matter such as humic acid, artificially synthesized organic matter such as dyes, and heavy metal ions such as copper ions are widely present in surface water such as rivers, lakes, and reservoirs in my country. The pollution of surface water bodies not only poses a threat to aquatic organisms, but also destroys the ecological environment, and ultimately endangers human health. In order to improve the quality of ...
