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.
 
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.
 
The determination of KF
Use MA-1 intelligent Carle Fischer moisture tester to measure water content
 
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.
 
Determination of iron content
  Preparation of standard iron solution
  Weigh ammonium iron(III) sulfate [FeNH4(SO4)2·12H2O] 0.863g .Placed in 1000mL volumetric flask, add water to dissolveand add sulfuric acid 2.5mL.Diluted with water to the mark, shake, as the stock solution.
   Before use, exact amount of stock solution 1mL, placed in 100mL flask, diluted with water to the mark and shake.
  Weigh 1g sample, placed in a crucible.Adding sodium carbonate 2g and mixed.Burning at 740 ℃,the residue is dissolved in dilute hydrochloric acid 15ml , displacing 50mL Nessler colorimetric tube , add dilute hydrochloric acid 4mL and ammonium persulfate 50mg , Diluted with water to make into 35mL, add 30% ammonium thiocyanate solution 3mL, plus the amount of water diluted into 50mL, shaked. If the color, take 1mL standard iron solution into 50mL Nessler colorimetric tube, add water to 25mL,4mL dilute hydrochloric acid and 50mg ammonium persulfate , diluted with water to 35mL, then plus 30% ammonium thiocyanate solution 3mL, plus the amount of water diluted into 50mL, shake comparisons.
