Abstract
The invention relates to a method for detecting underground water iron ion content, which is characterized by comprising the following steps: drafting a calibration curve; and determining total iron; wherein the method also comprises the determination of divalent iron: placing 2ml hydrochloric acid in a sample bottle having a plug while sampling, directly injecting a sample in the sample bottle, sealing and preserving for developing and measuring, taking a proper amount of sample while analyzing, directly adding a buffer solution and a phenanthroline solution, developing for 2 minutes, measuring absorbance at 510nm by taking water as a reference, and performing blank correction. According to the characteristic of underground water, the total iron and divalent iron ion can be determined by using a complexation principle, and the method has the advantages of high precision, good sensitivity and convenient operation.
Description
Technical field
The present invention relates to underground water detection technique field, particularly underground water iron ion content detection method.
Background technology
Iron is one of trace element of needed by human, and it participates in composition and the metabolism thereof of multiple enzyme in human body, relevant with the formation of haemoglobin, myoglobins again.Long-term not enough for iron, anemia with low hemoglobin, blood plasma level can be caused low inferior, affect the normal work of people, study, viability.Iron in food mainly exists with ferrous iron and ferric form, and ferrous iron is many directly to be absorbed by small intestinal epithelial cells, then is combined into ferritin with apoferritin, is transported to other positions of health and is utilized.And ferric iron must be reduced into ferrous iron in enteron aisle, just can be absorbed and used, its absorptivity is starkly lower than ferrous iron.Therefore, the content measuring total iron in food accurately can not reflect the height of the biological effectiveness of tapping a blast furnace.
Summary of the invention
The present invention is directed to the limitation of prior art, iron ion content detection method of supplying subsurface water, is characterized in that: said method comprising the steps of:
The drafting of calibration curve: pipette iron standard solution 0.2.00 successively, 4.00, 6.00, 8.00, 10.00m1 puts in 150m1 conical flask, add distilled water to 20mI, add hydrochloric acid 1m1 again, 10% hydrochloric acid is through amine 1m1, heating is boiled to solution and is remained 1-2ml, be cooled to room temperature, quantitatively be transferred in 50mI color-comparison tube, add Congored test paper, drip saturated sodium acetate solution to Congored test paper when reddening, add 2ml buffer solution, 0.2% adjacent phenanthrene is trembled beautiful jade solution 1m1, add water to graticule, shake up, after colour developing 15min, with cuvette, take water as reference, absorbance is measured at 510nm place, by the absorbance through blank correction, the concentration of iron is mapped.
Described method also comprises the mensuration of total iron: after sampling immediately by sample hcl acidifying to pH=2, get 20mI mixed sample during analysis in conical flask, then add hydrochloric acid 1ml, hydrochloric acid is through amine 1ml, and heating is boiled to solution and remained 0.2ml, filters.Once according to described drafting calibration curve operation, measure absorbance and do blank correction.
Described method also comprises ferrous mensuration: be placed in the water sample bottle of a tool plug by 2m1 hydrochloric acid during sampling, directly water sample is filled sample bottle, sealing is preserved standby colour developing and is measured, appropriate water sample is got during analysis, directly add buffer solution and neighbour's phenanthrene to tremble beautiful jade solution, colour developing 2min, sentencing water at 510nm is reference measurement absorbance, and makes blank correction.
The inventive method, according to the feature of underground water, utilizes complex scheme, and measure total iron and ferrous ion, this method precision is high, and sensitivity is good, easy to operate.
