Abstract

The invention aims to provide a trapping agent for adsorbing Pd2 and metal ions and a preparation method thereof. In order to realize the purpose, the following technical scheme is adopted: smashing and drying achnatherum splendens is smashed and dired, a certain amount of achnatherum splendens powder is selected, a little water is added, the pH value is adjusted to be 7.5-10.5 with 0.1 M of a sodium hydroxide solution, stirring is performed for reaction at the temperature of 20-30 DEG C for 60-80 min, 30% aquae hydrogenii dioxide is added for reaction for 60 min, a certain amount of bacillus licheniformis S1 is added after the reaction with lactose as a medium, and uniform stirring, suction filtering, washing, and drying are conducted to obtain the trapping agent.

Description

technical field [0001] The invention relates to the field of heavy metal ion adsorption, in particular to a collector for adsorbing Pd2+ metal ions and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of industrialization, the use of heavy metals has become more and more extensive, and the accompanying heavy metal pollution has become more and more serious. [0003] Frequent outbreaks of pollution accidents will destroy the normal physiological and metabolic activities of organisms, and even produce "three causes" (carcinogenic, teratogenic, and mutagenic) substances, which are extremely harmful to organisms and even affect generations. The increasing and harmfulness of heavy metal pollution load has attracted widespread attention from environmental scholars around the world. The existing traditional heavy metal treatment technology has problems such as relatively complicated process, high energy consumption, and easy to...
