Kaolin standard solution (for 100 mg/L)
After shaking up the concentrated kaolin standard solution (1000 mg/L) which is commercially
available or compounded by following the above mentioned table, immediately take the 200
mL and pour into the 2000 mL measuring flask and add tap water up to the gauge line.
Note
Make sure to use the pure water to dilute the TURB span calibration solution. Do not use tap
water, groundwater, or industrial water.
Kaolin standard solution can be deposited easily. Agitate the standard solution sufficiently before
calibration.
