Abstract

The invention discloses a fluorescent probe for detecting various metal ions in water, and a preparation method and application thereof. The probe is made up of symmetrical tetramethyl cucurbit [6] uril and trans-4-4(Dimethylamino)styryl-1-methylpyridine iodine. The preparation method comprises the following steps: dissolving tetramethyl cucurbit [6] uril in water to obtain a solution A; dissolving trans-4-4(Dimethylamino)styryl-1-methylpyridine iodine in water to obtain a solution B; and mixing the solution A and the solution B, and reacting at normal temperature to obtain the probe. The probe is mainly used to detect caesium, strontium, barium, iron, chromium, mercury, europium,thulium and/or ytterbium ions in water. The probe disclosed by the invention can be used to detect various ionsof caesium, strontium, barium, iron, chromium, mercury, europium,thulium and/or ytterbium in water, and has the characteristics of high sensitivity, low detection cost, simple sample processing, convenient operation, rapid determination and real-time detection.

Description

technical field [0001] The invention relates to a fluorescent probe for detecting metal ions in water and its preparation method and application, in particular to a fluorescent probe for detecting cesium, strontium, barium, iron, chromium, mercury, europium, thulium and / or ytterbium ions in water Fluorescent probes and their preparation methods and applications. Background technique [0002] At present, the detection and analysis of cesium, strontium, barium, iron, chromium, mercury, europium, thulium and ytterbium ions in drinking water are mainly carried out by using absorption / emission spectroscopy, ion spectroscopy, inductively coupled plasma atomic emission spectrometry and inductive Coupled plasma mass spectrometry, etc. These methods have high accuracy and sensitivity, but these detection equipment are expensive and require very professional detection technicians to complete, and the detection cost is relatively high. [0003] Fluorescent probe is a new type of dete...
