Abstract

The invention discloses a method for preparing ammonia nitrogen sorbent by utilizing abandoned strawberry leaves and the application of the sorbent. The abandoned strawberry leaves are used as raw materials, and the raw materials are washed, aired, dried and crashed and then are sieved through a standard sieve to obtain the sorbent with the mesh number of 30 to 200. The sorbent is added to a water solution containing ammonia nitrogen and is surged for 20 hours on an oscillator, and the ammonia nitrogen in the water can be effectively removed. The raw materials of the sorbent recycles agricultural wastes, the cost is low, the preparation process is simple, and the raw materials have highly specific adsorption performance to the ammonia nitrogen in the water.
