Embodiment 1

[0010] Example 1 (preparation experiment):

[0011] 1) To anhydrous ethanol (50mL), add 0.1 mol of sodium metal block. After the reaction is complete, add ethyl cyanoacetate (0.1 mol, 98%, Zibo Yixin Chemical Co., Ltd.), thiourea (0.1 mol, 99%). %, Shijiazhuang Sidiano Fine Chemical Co., Ltd.), 2,2-Dimethyl-4-pentenal (0.1 mol, 98%, Henan Pusai Chemical Products Co., Ltd.), stir at room temperature for 24 hours, pour Add 0.1 N HCl to ice water at 0°C to produce precipitation, filter, dry the solid phase and recrystallize from DMF / water (first add a small amount of water, heat to boiling, add DMF dropwise until all is dissolved, then cool to room temperature naturally, Filtration to obtain the precipitated solid) to obtain an intermediate. The yield was 84.5%. Elemental analysis (%) calculated value: C, 56.15; H, 5.57; N, 17.86; O, 6.80; S, 13.62. Measured value: C, 56.12; H, 5.61; N, 17.89; O, 6.82; S, 13.56. IR (KBr, cm-1): 557, 728, 764, 912, 991, 1044, 1113, 1207, 1274, 13...

Embodiment 2

[0015] Example 2 (Iodine adsorption experiment):

[0016] Weigh the elemental iodine, prepare 300 mL of an aqueous solution with a concentration of 0.25 g iodine / L, put it into a 1000 mL conical flask, add 0.01 g of the product of this application, the mouth of the bottle is sealed, and shake at 30 rpm at room temperature (about 20°C). Stop shaking every 1 minute, take samples, and measure the iodine concentration in the solution by GBT5750.5-2006 (dilution colorimetry). The mass of iodine absorbed by the product = the initial volume of the solution * the initial detection concentration-the current detection concentration * the remaining solution volume-∑ each detection concentration * each detection volume of solution. Saturated adsorption capacity = mass of iodine adsorbed by product / mass of product. In the experiment, the adsorption equilibrium was reached after 9 minutes, and the measured saturated adsorption capacity was 4.83 g iodine / g. The saturated product at this tim...

Abstract

The hypothyroidism, autoimmune thyroidism, papillary thyroid cancer and the like can be caused by excessive iodine ingested by a human body. At present, some water bodies in China have a certain degree of iodine pollution and greatly exceed the water body environment quality standard. The invention synthesizes a material for adsorbing iodine molecules in a water body, and the material has relatively large adsorption capacity for iodine molecules in water.

Description

Technical field [0001] The invention belongs to the field of water treatment, and discloses a material for adsorbing iodine in water and a synthesis method thereof. Background technique [0002] Excessive intake of iodine in the human body can cause hypothyroidism, autoimmune thyroid disease and papillary thyroid cancer. At present, some water bodies in my country have a certain degree of iodine pollution, which greatly exceeds the environmental quality standards of water bodies. The current existing materials have relatively small adsorption capacity for iodine molecules. The invention synthesizes a material for adsorbing iodine molecules in water, and has a larger adsorption capacity for iodine molecules in water. Summary of the invention [0003] The scheme of the application synthesizes a new material with high adsorption capacity for iodine molecules in water. The structural formula is shown below. [0004] [0005] The synthesis method is: [0006] 1) Add metallic sodium bl...
