| titleOfInvention | Preparation method and application of fluorescent test strip for analyzing trace water in organic reagent |
| abstract | The invention belongs to the field of energy chemical industry detection, and particularly relates to a preparation method and application of a trace water analysis fluorescent test strip in an organic reagent. The preparation method of the fluorescent test strip comprises the following steps: covalently bonding melamine and QG by glutaraldehyde, and sequentially adding 2-aminoterephthalic acid and zinc nitrate for coordination to form MOFs; (2) settling MOFs by adopting triethylamine, washing by adopting DMF, and drying to obtain a nano composite material; (3) the nano composite material is loaded on the test strip to prepare the water-sensitive fluorescent test strip. When the test strip is used for detecting trace moisture in an organic reagent, the test strip is simple to operate, short in detection time, high in sensitivity, portable in detection system, and suitable for quickly, sensitively, automatically, and micro-detecting trace moisture content in organic reagent samples such as ethanol, aviation gasoline and DMF (dimethyl formamide), and can be applied on site, and the detection result is consistent with the quantitative result of a classical Karl Fischer method. |
