Abstract

A method utilizing sloanea sinensis leaves for green synthesis of water-soluble nano-iron includes the steps: firstly, preparing sloanea sinensis leaf solution according to the standard of adding 1.00-5.00g of sloanea sinensis leaf powder into 100.0mL of deoxygenated water, and subjecting the sloanea sinensis leaf solution to water bath in hot water at the temperature of 50-70 DEG C for 30-120 minutes; centrifuging the heated sloanea sinensis leaf solution via a centrifugal machine at the rotating speed of 3000-6000r / min for 5-10min to obtain supernatant liquor, namely sloanea sinensis leaf extract; and according to the standard of adding 2mL-10.0mL of deoxygenated iron salt water solution with the molar concentration of 0.10mol / L into 40.0mL of sloanea sinensis leaf extract, and uniformly shaking to obtain the water-soluble nano-iron. The method is simple in operation and low in cost, and the prepared nano-iron has excellent catalytic performance and has good application value in the aspect of catalyzing and degrading organic matters difficult to degrade.

Description

technical field [0001] The invention relates to a preparation method of water-soluble nano-iron, in particular to a method for synthesizing water-soluble nano-iron by utilizing the green leaves of monkey joy tree. Background technique [0002] Due to its strong reducibility and excellent catalytic performance, nano-iron plays an important role in the fields of wastewater treatment, soil remediation, and catalytic degradation. Therefore, the preparation method of nano-iron has attracted people's attention. The commonly used method for preparing nano-iron is the reduction method using a strong reducing agent. [0003] NaBH is commonly used in strong reducing agent reduction method 4 , N 2 h 4 Prepare iron nanoparticles by reducing iron salts. NaBH 4 , N 2 h 4 It is inflammable and explosive, and its transportation and preparation process have a great impact on the environment, and the cost is relatively high. Toda Kogyo Ltd. started using hydrogen gas as a reducing age...
