Dye Uraninate A.

Description

<P> Uranha and the use is considered low-budget. The consumption is higher than that of the top grade uranain. <br /> Instructions for use of uranium and fluorescein sodium </ p> <p> Uranies and fluorescein sodium - organic dyes, when dissolved in water, give a strong green fluorescence. Used in the form of a solution with a mass fraction of about 1%. </ P> <p> 1. Preparation of the solution is a torn. <br /> The device with a stirring device is loaded 1 m³ of water and with stirring added 10 g. The dissolution process is carried out at 20-25 ° C, the completeness of dissolution is determined visually on the absence of precipitate. </ P> <p> 2. Preparation of the solution of fluorescein sodium. <br /> The device with a stirring device is loaded 1 m³ of water and with stirring, 20 g. Fluorescein sodium is added. The dissolution process is carried out at 20-25 ° C, the completeness of dissolution is determined visually by the absence of precipitate. </ P> <p> Application <br /> any of the solutions obtained can be used to determine water leakage. A noticeable fluorescence is observed with a mass fraction of a storage (sodium salt of fluorescein) 2.5x10-6%. At water consumption of 1m³ / h, the consumption of a solution of a flatulent (sodium salt of fluoresinetzin) with a mass fraction of 1% will be 2.5 sm³ / h. </ P> <p> 3. Simplified way. 1-3 grams of uranine and a / s or 5 g of fluorescein of sodium are added to 1-3 grams of sodium fluorescein.
