Embodiment 1

[0032] In this embodiment, a method for preparing a phosphorus-removing adsorbent by microwave-assisted salting-out method, the specific steps are as follows:

[0033] 1) Raw material selection: select well-preserved and undeteriorated eucalyptus leaves as raw materials;

[0034] 2) Slicing: cut the eucalyptus leaf raw material into flakes with scissors;

[0035] 3) Cooking: put the sliced ​​eucalyptus leaves into boiling water and boil for 30 minutes, then clean them for later use; put the cleaned flaky eucalyptus leaves into a large beaker;

[0036] 4) Prepare sodium chloride solution: prepare a sodium chloride solution with a concentration of 0.5mol / L, pour it into a prepared small beaker, pour 50mL, and label it;

[0037] 5) Microwave-assisted solution soaking: put the boiled flaky eucalyptus leaves into a small beaker filled with 0.5mol / L sodium chloride solution, and put the small beaker into a microwave oven for 20 minutes;

[0038] 6) Cleaning: Take out the flaky euc...

Description

technical field [0001] The invention relates to a method for preparing a phosphorus-removing adsorbent by using a microwave-assisted salting-out method, which belongs to an environment-friendly production method of an original ecological green biological adsorbent. Background technique [0002] At present, with the development of science and technology and the rapid development of heavy industry, phosphorus-containing chemicals are excessively used in production, and some enterprises do not discharge some waste liquid into water bodies in accordance with national discharge standards, which will cause algae or Other aquatic plants grow rapidly and multiply in large numbers, causing the oxygen content in the water to drop, and the organisms in the water die due to hypoxia, which further aggravates the pollution of the water body. In severe cases, navigation will be blocked, leading to the extinction of still water ecosystems such as lakes, so it is of great significance to rem...
