Textile sizing slurry COD /
Test Method of BOD
1 Scope
This standard specifies the method for textile sizing slurry for chemical oxygen demand (COD)/BOD (BOD5) assay.
This standard applies to slurry for chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) Determination/five days in textile sizing.
This standard sample slurry was detected, the chemical oxygen demand (COD) determination limit of 15mg/L, the upper limit is measured
1000mg/L, a chlorine ion concentration should not exceed 1000mg/L; the chemical oxygen demand (COD) greater than 1000mg/L or chloride ions
Sample content greater than 1000mg/L can be measured after appropriate dilution.
The standard detection sample slurry was made, biochemical oxygen demand (BOD5) measuring range is 2mg/L ~ 6000mg/L; for
In biochemical oxygen demand (BOD5) sample is greater than 6000mg/L can be measured after appropriate dilution.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
COD chemicaloxygendemand; COD
Under certain conditions, the potassium dichromate oxidation treatment in a sample of dissolved substances and suspended solids consumed potassium dichromate corresponding oxygen
Mass concentration, 1mol potassium dichromate (1/6K2Cr2O7) 1mol equivalent of oxygen (1/2O), expressed in COD.
3.2
BOD biochemicaloxygendemandafter5days; BOD5
Under certain conditions, the presence of microbial decomposition of certain substances in the water can be oxidized, in particular biochemical organic matter carried through
The amount of dissolved oxygen consumed by the process (expressed in mass concentration). Usually it refers to a sample filled completely closed oxygen bottle in
(20 ± 1) ℃ dark culture 5d ± 4h or (2 5) d ± 4h [first in the dark 0 ℃ ~ 4 ℃ cultured 2d, followed by (20 ± 1) ℃ of
Dark culture 5d, namely culture (2 5) d], were measured before and after the culture concentration of dissolved oxygen in the sample, before and after the culture by the mass of dissolved oxygen
Differential concentrations, calculate the amount of oxygen consumed per liter of sample, expressed as BOD5.
Preparation of 4 samples
4.1 paste. paste Weigh the weighing 5g, amount of 995mL of distilled water into a 2000mL beaker, the beaker was placed a magnetic stirring add
On heat, stirring slurry was added slowly, then begin heating to 95 ℃ ~ 97 ℃. After the slurry was continued constant stirring 60min, cooling
Tested.
