Abstract

The invention belongs to the field of chemical detection, and particularly relates to a method for detecting oxalic acid by using quantum dots, which is characterized by comprising the following steps: (1) preparing a detection solution, adding a bivalent copper ion solution and a buffer solution into the detection solution, and incubating to obtain a first reaction solution; (2) adding a quantum dot solution into the first reaction solution, and incubating to obtain a second reaction solution; and (3) detecting the concentration of oxalic acid in the detection solution by measuring a fluorescence spectrum. The invention provides a simple, high-sensitivity, rapid, low-cost, quantitative and specific method for detecting the oxalic acid content, and the method has a wide application prospect in the fields of clinical diagnosis (such as caluria oxalate), environment, chemical industry and the like.

[0002] The invention belongs to the field of chemical detection, and in particular relates to a method and application for detecting oxalic acid by using quantum dots. Background technique

[0003] Urolithiasis is a common disease affecting 5% to 8.8% of the global population with a 5-year recurrence rate of up to 50%. Urolithiasis mainly includes calcium oxalate and calcium urate, and calcium oxalate stones are the most common type of urolithiasis. Urolithiasis can easily form when urinary oxalate levels are supersaturated. Oxalate in urine may be derived from diet or endogenous synthesis in the liver. In clinical practice, measurement of urinary oxalate content in stone formers can ide...
