Description

technical field

[0001] The invention belongs to the technical field of electrochemical analysis, and in particular relates to a novel composite modified electrode and its application in the detection of aluminum ions and xylitol. Background technique

[0002] The intake sources of aluminum in the human body mainly include: water sources, animals and plants, food additives and various containers. After the food containing too much aluminum ions is ingested by the human body, it is difficult to excrete it from the body and will be deposited in the body. Certain hazards, such as causing chronic toxic side effects. In addition, the compound derivatives of aluminum are widely used in daily diet as food additives. The aluminum content in fried dough sticks, steamed buns, instant noodles, puffed food, etc. are generally exceeding the standard. Long-term intake of excessive aluminum has harmful effects on the human body that cannot be ignored. , therefore, how to quickly and accura...
