Abstract

The invention discloses a probe-N,N-dis(4-diethylamine salicylidene)ethylenediamine for detecting manganese ions in water quality based on a naked eye visual colorimetry and a manganese ions detection kit and a test paper based on the probes. The manganese ions probe can be synthesized by one step reaction, a detection mechanism is based on the complexing reaction, and the naked eye visual colorimetry is used for detecting the manganese ions in a liquid to be measured. The manganese ions detection kit comprises a reagent storage liquid 1 and a reagent storage liquid 2, wherein the reagent storage liquid 1 is a HEPES buffer, and the reagent storage liquid 2 is a solution of N,N-dis(4-diethylamine salicylidene)ethylenediamine. The manganese ions detection test paper is composed of the N,N-dis(4-diethylamine salicylidene)ethylenediamine and a solid carrier. The invention can realize a rapid quantitative or semi-quantitative detection with high sensitivity and high selectivity for microscale manganese ions in the water quality. The probe has the advantages of simple synthesis route and low cost, and has large application prospect in the environmental protection field.

Description

technical field

[0001] The present invention relates to the preparation and application of a probe for detecting manganese ions based on naked-eye visual colorimetry, in particular to the synthesis of N,N-bis(4-diethylaminosalicylidene)ethylenediamine The preparation and application of a manganese ion detection kit and test paper based on the probe belong to the technical field of analytical chemistry detection. technical background

[0002] Manganese is one of the essential trace elements for the human body, but excessive intake of manganese can easily cause manganese poisoning. Especially in fields such as electric welding, mining, and dry battery production, it is easy to inhale manganese for a long time and cause chronic manganese poisoning. Manganese poisoning has the manifestations of neurasthenia syndrome such as dizziness, headache, easy fatigue, sleep disturbance and forgetfulness, as well as symptoms such as limb pain, weakness and heaviness of lower limbs. In se...
