Method for rapidly determining fluoride content in drinking water surrounding furniture plant

Abstract

The invention discloses a method for rapidly determining the fluoride content in the drinking water surrounding a furniture plant. The method comprises the steps of weighing standard sodium fluoride, and shifting sodium fluoride into a volumetric flask after dissolving sodium fluoride with water; weighing sodium acetate and dissolving sodium acetate in water; weighing sodium citrate dihydrate and sodium nitrate, dissolving sodium citrate dihydrate and sodium nitrate in water, and adjusting the pH value with hydrochloric acid; siphoning off a proper amount of water sample by a pipette, placing the water sample in the volumetric flask, and adjusting the pH value to be neutral with sodium acetate or hydrochloric acid solution, adding a conditioning buffer solution, diluting with water to a reticle, shifting into a polyethylene cup, placing a plastic stirrer, inserting an electrode, continuously stirring the solution, and reading the potential value while continuously stirring the solution when the potential becomes stabilized, fully washing the electrode with water each time before measurement, absorbing to remove water by the filter paper, searching in a standard curve to obtain the fluoride concentration in a test solution according to the measured value of millivolts, and calculating the fluoride content according to the dilution ratio of the water sample. The method is simple and convenient in measuring process, and accurate in measurement result. Based on the method, people can trustingly drink the tested drinking water, so that the health of people is ensured.

Description

technical field [0001] The invention relates to a method, in particular to a method for rapidly measuring the fluoride content in drinking water around a furniture workshop. Background technique [0002] Drinking water refers to water that can be directly supplied to the human body for drinking without treatment. Water is the main component of body fluid, and is an important substance that constitutes cells, tissue fluid, plasma, etc. As the medium of all chemical reactions in the body, water is a platform for the transportation of various nutrients and substances. With its 40% market share, packaged drinking water has firmly ranked the top spot in the national beverage market. In the industry, pure water, natural mineral water and mineral water manufacturers account for the largest proportion. Consumers' preferences for drinking water have changed, and the strategic focus of enterprises has also shifted to natural mineral water following the market. From January to Dece...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned problems that the existing measurement process of fluoride in drinking water is complicated, and the measurement result has large error, and people drink the drinking water with inaccurate measurement result for a long time, which will cause harm to the body. A method for quickly measuring the fluoride content in drinking water around the furniture factory building. The method is simple and easy to measure, and the result is accurate, so that people can drink the tested drinking water with confidence, ensuring people's health, and solving the existing problems. The determination process of fluoride in drinking water is complicated, and the measurement error is large. If people drink drinking water with inaccurate measurement results for a long time, it will cause harm to the body.
