Online aluminum content detection system and method

Abstract

The invention discloses an online aluminum content detection system and method. The method comprises the following steps: performing zero setting and exhausting of a plunger pump; emptying a reactiontank; quantitatively conveying a water sample into the reaction tank and detecting the light intensity penetrating the water sample at the moment; quantitatively conveying a related aluminum content detection reagent into the reaction tank, standing for 15 minutes, performing diluting, performing bubbling and stirring for 15 minutes, detecting the light intensity of light penetrating a mixed solution currently, and calculating the absorbance of the mixed solution; detecting the absorbance of a plurality of water sample mixed solutions with known aluminum contents, and establishing a linear curve of the absorbance and the aluminum content; and detecting the absorbance of an unknown water sample according to the linear curve to obtain the aluminum content in the water sample. The online aluminum content detection system and method provided by the invention have the advantages of rapidness, simplicity, great convenience, short measurement period, high sensitivity, high precision and capability of realizing online detection.

Description

technical field [0001] The invention relates to an on-line aluminum content detection system and method, belonging to the technical field of water quality detection. Background technique [0002] Aluminum has always been considered a non-toxic element, but research in recent years has shown that aluminum has an important impact on human health. Aluminum content is one of the routine indicators in the "Drinking Water Hygienic Standard", and the limit is 0.2mg / L. Medical reports indicate that excessive intake of aluminum by the human body is not good for health, because aluminum can accumulate in the human brain tissue and neuron cells, which will greatly damage the human body's memory, and make people's thinking slow and judgment ability decline. Even lead to nerve paralysis. In patients with some neurological diseases such as neurofibrotic disease, degenerative brain degeneration, and Alzheimer's disease, it is found that the aluminum content in their brain tissue is highe...

Problems solved by technology

[0003] Although the current national standard uses spectrophotometry to measure aluminum content, this method has disadvantages such as time-consuming, material consumption, inconvenient operation, and high labor intensity for analysts; and it is very easy to introduce errors, resulting in a decrease in the reproducibility of test data, making it difficult to Realize online and remote analysis
