The determination of UV absorbance

  A certain amount of the sample was weighed to the nearest 0.0001g, into 10ml volumetric flask, 

after constant volume with pure water, at a specific wavelength by 2cm cuvette was measured by

 UV spectrophotometer.

 

The determination of KF

Use MA-1 intelligent Carle Fischer moisture tester to measure water content

 

Detection of heavy metals

     The meaning of heavy metals of this act is under the specified experimental condition, which can 

coloration effects with sodium sulfide or thioacetamide  .The glasses of preparation or storage is not 

allowed to contain lead.

5.8.1  Reagents

  a) Lead dinitrate:1μg/mL

   b) Sodium hydroxide :10%(m/v)

   c) Sodium sulfide :10%(m/v)

5.8.2  Preparation of lead standard solution

     Weigh lead dinitrate  0.1599g ,relocated to 1000mL volumetric flask, plus nitric acid 5mL and

     water 50mL, diluted with water to the mark , shake, as the stock solution.

5.8.3 Determination of step

   Before use, the exact amount of stock solution 1mL, relocated to a 100ml volumetric flask, dilute

   with water to the mark, shake, limit the use of the day .

   Weigh sample 1g, after adding sodium hydroxide solution 5mL and 20mL of water to dissolve, 

set Nessler colorimetric tube, add 5 drops of sodium sulfide , shake , compared the color with 5mL 

lead standard solution after the same treatment,  not deeper

 

Determination of melting point

   Instrument:

   Micro melting point apparatus WRS-2A, Melting point tubes

  Determination of step:

Open switch, stable 20min.

First set the starting temperature than the melting point of the low 10 ℃, heating rate 2 ℃ / min.

The sample was grind as fine as possible and load in a clean, dry melting point pipe ,until the sample

 was compressed into about 1cm high .When the actual temperature reaches the set temperature and

 stabilized . Inserted into the capillary with the sample, the simultaneous determination of three.

 

The determination of PH

Weigh a certain amount of samples into test tube, add a certain amount of water, shake and dissolve, 

determination of the pH used have been calibrated pH meter.
