Abstract

The invention discloses a resonance scattering method for controlling the catalytic activity of a graphene oxide nanoribbon by using a sodium tetraphenylborate ligand to measure K<+>. The method is characterized by comprising the steps of (1) preparing a K<+> standard solution system with known concentration; (2) preparing a bank control solution system; (3) calculating deltaI=I-I0; (4) making a work curve for a concentration relationship of the K<+> by using deltaI; (5) calculating deltaIsample=Isample-I0; and (6) calculating the content of the K<+> of the sample solution according to the work curve in the step (4). According to the measurement method, the catalytic activity of a nano-enzyme is controlled by adopting the ligand, and the method is simple, convenient, fast and high in sensitivity.

Description

technical field [0001] The invention relates to the field of analytical chemistry, in particular to a resonance scattering spectroscopic determination of K by regulating the catalytic activity of graphene oxide nanobelts with tetraphenylborate sodium ligands. + Methods. Background technique [0002] Potassium ion (K + ) is an important physiological element, and Na + Together, they play an extremely important role in maintaining cell metabolism, regulating body fluid osmotic pressure, maintaining acid-base balance, and maintaining cell stress functions. At the same time, potassium ions play different roles in the process of biological growth, including neurotransmission , enzyme activation, apoptosis, regulation of blood pressure and the concentration of other ions in cells. K between intracellular and extracellular fluid + Disturbances in ion concentration are invariably associated with a range of diseases including alcoholism, anorexia, bulimia, AIDS and kidney disease...
