Embodiment Construction

[0022] Please check image 3 , a method for preparing a zirconium oxide-loaded pomelo peel adsorbent of the present embodiment, comprising the following steps:

[0023] (1) Cut the fresh pomelo peel into blocks (about 10mm), wash with water, dry in a constant temperature drying oven at 50°C until constant weight, and cut into small particles of 2-4mm.

[0024] (2) Weigh 2.00g of dried pomelo peel granules, place in a 150mL Erlenmeyer flask, add 100g of zirconium oxychloride solution with a mass fraction of 40%, place in a shaker for 2h, set the temperature at 298.15K, The speed is 150r / min.

[0025] (3) Filter the pomelo peel impregnated with zirconium oxychloride, collect it into a petri dish, and dry it in a constant temperature drying oven at 80°C overnight (12-24h).

[0026] (4) Put the dried zirconium-loaded pomelo peel in a tube furnace, pyrolyze it at 200°C for 1 hour, take out the grapefruit peel after cooling to room temperature, and obtain zirconium oxide-loaded gr...

Abstract

The invention discloses a preparation method and application of a zirconium oxide-loaded shaddock peel adsorbent. Zirconium oxide is loaded on granular shaddock peel through a dipping-pyrolysis method, and a novel modified shaddock peel adsorbent material Zr-PP is prepared. The preparation method of the adsorbent is simple, preparation raw materials are wide in source and low in cost, and phosphates in water can be rapidly and effectively removed, so that the risk of causing lake eutrophication is reduced, and the economic loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of novel material preparation, and in particular relates to a preparation method and application of zirconium oxide-loaded pomelo peel adsorbent. Background technique [0002] Phosphorus is one of the indispensable elements for life activities and has important physiological functions. However, with the development of society and economy, phosphate-rich industrial wastewater and domestic sewage are discharged into water bodies, and unreasonable use of chemical fertilizers causes phosphorus-containing agricultural wastewater to pollute surface water. Excessive phosphate causes rapid growth of algae and microorganisms in the water, consumes dissolved oxygen in the water, causes fish and shrimp to die, and causes eutrophication of the water. Eutrophication not only destroys aquatic ecosystems, but also causes severe economic losses. Algae blooms and fish and shrimp deaths directly lead to economic losses in t...
