Abstract
The invention discloses lead ion detection test paper, and a preparation method and a use method thereof. The detection test paper is prepared through taking out filter paper after being infiltrated in a impregnation liquid and drying; the impregnation liquid comprises an impregnation liquid I consisting of dithizone and trichloromethane and an impregnation liquid II consisting of phenanthroline, potassium rhodanate and distilled water; in the detection test paper, dithizone is used as a chromogenic agent, a 50 mL 0.1 M trihydroxymethyl aminomethane solution and 14.7 mL 0.1 N hydrochloric acid are uniformly mixed, and then water is added to dilute till the volume is 100 mL, and an activator is prepared through uniformly mixing. The preparation is simple, the cost is low, the use is convenient, the environment is pollution-free, which is beneficial to environment protection, the test range is wide, professional are not required, and the lead ion detection test paper, the preparation method and the use method are especially suitable for quick field test on the lead content.
Description
Technical field
The present invention relates to a kind of lead ion detection technique, relate in particular to and a kind ofly using dithizone as lead ion Test paper of developer and preparation method thereof and using method.
Background technology
Lead contamination is one of five large heavy metal pollutions.In recent years, China's industry and communications fast development, lead contamination is on the rise, and has become large public hazards that affect health of people.
The main cause that causes chronic lead poisoning is environmental pollution, lead ore exploitation, plumbous smelting, foundry goods, water plate, welding, spraying, lead fume, the lead dust of the techniques such as accumulator manufacture, greasepaint, take leaded Chinese medicine, as Heixi Dan, minium, red lead with drink for a long time the wine in leaded tinpot, all can cause saturnism.Atmosphere pollution, water source and the crops such as leaded waste gas, waste water, waste residue, finally can jeopardize the mankind.
Saturnism be take inorganic saturnism as common, mainly damages nervous system, digestive system, hemopoietic system and kidney.In recent years, the impact of Effects of Lead Exposure Endocrine, reproductive system, fertility also draws attention.According to surveying and determination, when the blood in human body in lead concentration is crossed 30 micrograms/100 milliliter, just there will be the symptoms such as dizziness, muscle arthritis, insomnia, anaemia, stomachache, irregular menstruation.
Pollutant limit index regulation in state food, fruit lead is limited the quantity of and is limited the quantity of and limit the quantity of and limit the quantity of and limit the quantity of as 0.5mg/Kg for 0.05mg/Kg, fish lead for 5mg/Kg, sweet milk lead for 0.05mg/Kg, tealeaves lead for 0.1mg/Kg, fruit juice lead.
Therefore, lead content detects significant in fields such as commercial production, environment measuring, agriculture application, medical science, food securities.The detection method of lead content has extraction spectrophotometric method, GFAAS (graphite furnace atomic absorption spectrometry), flame atomic absorption spectrometry, potentiometric stripping etc. at present, these detection methods, not only require to have laboratory condition, and detection time is longer, operate loaded down with trivial details, expense is also higher, is unfavorable for realizing field quick detection.
