Preparation method of zero-valent Pd/Cu modified moso bamboo biomorphic composite material and application thereof

Abstract

The invention discloses a preparation method of a zero-valent Pd / Cu modified moso bamboo biomorphic composite material and an application thereof. The method comprises the following steps: washing the moso bamboos cut into strips with deionized water, drying the moso bamboos, calcining the moso bamboos in a tubular furnace in a nitrogen atmosphere at 600 DEG C for 4 hours, and cooling, grinding and sieving the moso bamboos to obtain moso bamboo carbon; weighing PdCl2 and CuCl2 with different mass ratios, adding the PdCl2 and the CuCl2 into a 100mL glass bottle with a plug, dissolving the PdCl2 and the CuCl2 with 50mL of deionized water, weighing 0.5600 g of moso bamboo carbon, adding the moso bamboo carbon into the glass bottle, plugging a sealing plug, introducing nitrogen for 20 minutes, and then carrying out ultrasonic treatment for 1 hour; and weighing excessive NaBH4, dissolving the NaBH4 in 20mL of deionized water, dropwise adding the NaBH4 by using a dropper, oscillating the NaBH4 at the rotating speed of 130rpm for 30 minutes, repeatedly cleaning the NaBH4 by using absolute ethyl alcohol and deionized water, carrying out suction filtration, and drying the NaBH4 in a drying oven at the temperature of 40 DEG C to obtain the zero-valent Pd / Cu modified moso bamboo biomorphic composite material. The preparation process is simple, the cost is low, a good removal effect on nitrate in water is achieved, the material after the electrocatalytic reduction reaction can be recycled through suction filtration, and the utilization effect is high.

Description

technical field [0001] The invention belongs to the technical field of waste resource utilization and water treatment, and in particular relates to a preparation method and application of a zero-valent Pd / Cu modified moso bamboo relic composite material. Background technique [0002] With the development of social production and the improvement of living standards in our country, the discharge of domestic sewage and industrial wastewater into the natural environment has increased rapidly. At present, the groundwater and surface water sources of many cities and regions in our country are subject to varying degrees of NO 3 -N pollution seriously threatens the health of people who use water. Nitrate is also a common pollutant in surface water and groundwater. The accumulation of nitrate in nature is mainly caused by human activities such as the combustion of fossil fuels, the excessive use of nitrogen-rich fertilizers, and the discharge of domestic and industrial sewage. NO in...
