Abstract

The invention relates to the technical field of biomass modified adsorbent materials, in particular to a method for preparing a modified macadamia shell adsorbent. The method includes the following steps: after being subjected to basic treatments, namely cleaning, smashing and sieving, macadamia shells are subjected to acidizing treatment; the acidized macadamia shell powder is cleaned to neutral and then subjected to ammonium hydroxide; the product obtained in the previous step is then dried and ground to form an adsorbent, so that the capacity of the adsorbent for adsorbing reactive brilliant red reaches 240-250 mg / g in an acidic condition, the capacity of the adsorbent for adsorbing cationic dyes reaches 200 mg / g, and the capacity of the adsorbent for adsorbing methylene blue reaches 400 mg / g. The modified macadamia shell adsorbent provided by the invention has the advantages of being good in chemical stability, high in mechanical strength and easier in regeneration.

Description

technical field

[0001] The invention relates to the technical field of biomass modified adsorbent materials, in particular to a method for preparing a modified macadamia nut shell adsorbent. Background technique

[0002] With the rapid development of modern industry, the discharge of printing and dyeing wastewater from textile factories, printing factories, paint factories and other factories has increased year by year, causing serious impact on environmental pollution, which has aroused widespread concern. Printing and dyeing wastewater has the characteristics of deep color, complex composition, high content of organic pollutants and large changes in water quality. When it is randomly discharged into the water body, it not only affects the appearance and smell of the natural water body, but also affects the growth and reproduction of animals and plants in the water, thereby destroying the ecological balance and affecting human health and living environment. At present, the...
