Preparation method of hybrid composite material iron ion fluorescent probe, and product and application of product

The invention discloses a preparation method of a hybrid composite material iron ion fluorescent probe. The preparation method comprises the following steps: dissolving dicumarol and lysine in an aqueous solution, performing a reaction at 205-210 DEG C for 10-13 h, centrifuging to remove large particles, filtering the obtained supernatant by a 0.25-0.30 [mu]m filter membrane, taking the supernatant, and performing dialysis and freeze drying to obtain the product. The invention also discloses an application of the product in detection of Fe in an aqueous phase. The fluorescent probe can beused for detecting the content of Fe in the aqueous solution, has high sensitivity, avoids the use of an organic solvent, and is beneficial to the practical application of the fluorescent probe in organisms and water environments. 本发明公开了一种杂化复合材料铁离子荧光探针的制备方法，将双羟香豆素和赖氨酸在溶于水溶液中，在205℃～210℃下反应10～13小时，离心，除去大颗粒，上清液经0.25μm～0.30μm滤膜过滤，取上清液，透析，冻干，得到产品，还公开了该产品在水相中检测Fe的应用，该荧光探针可用于水溶液中Fe的含量检测，灵敏度高，避免了有机溶剂的使用，有利于其在生物体内和水体环境中的实际应用。
