the determination of loss on drying

weigh a sample of approximately 2g (weighing accuracy 0.0001g),record the weight of m,the sample was placed in a petri dish constant weight (weight recorded as m0), the tile, the thickness of not more than 5mm, into the oven (as next dish cover removed) drying at 105-110 ℃ 3 hours.when removing, make sure the dish cover,be placed in a desiccator to cool, then weighed and the weight (including surface dish) m1.

loss on drying in accordance with the following formula:

where:

m-- sample, g

m0-- dish, g

m1-- after drying the quality of the sample and the dish, g

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.

the determination of residue on ignition

first the griddle was burning 30 minutes at 600 ± 50 ℃, cooled and then weighed on a silica gel drier.taking 1g sample was placed in a crucible and weighed, with 2ml sulfuric acid (5.5ml98% sulfuric acid diluted to 100ml) wetting the sample which was slowly heated until the sample completely low zoom.cooling,using 2ml sulfuric acid (5.5ml98% sulfuric acid diluted to 100ml) to wet the sample, which was slowly heated until no white smoke, and then placed at 600 ±50℃ calcined to obtain the residue, to ensure that the entire process does not produce white smoke.cooling griddle silica gel dryer and then weighed to calculate the mass of the residue.

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.
