SLIDE & MIDGET COMPARATOR TESTS

ORTHOPHOSPHATES & POLYPHOSPHATES IN GENERAL

This method is based on the formation of phosphomolybdic acid, which is subsequently

reduced with stannous chloride to produce a blue color whose intensity is proportional to

the phosphate (PO

) present. Interferences are reduced to a minimum. The presence of

10,000 ppm of silica (SiO

), 100 ppm of ferrous or ferric iron, or 1000 ppm of sulte causes

no error.

The water to be tested must be carefully ltered with a good grade of lter paper to free it

from sludge and scale. Mere traces of sludge will cause serious errors.

If repeated ltration does not clarify the water, add 0.5 g potassium nitrate crystals to 25 mL

of the sample water, heat to boiling, cool, dilute to 25 mL with distilled water, and lter.

If the water is very highly colored by tannin or other highly colored organic matter, so that a

phosphate determination is dicult or impossible, it can be eectively decolorized with

activated charcoal. Add half a teaspoon of activated charcoal to a pint container of the

colored sample water. Close the container and shake sample well. Decolorization should

take place in 5 to 15 minutes. The treated sample is then ltered as instructed above. From

this point on follow the procedure outlined in the Orthophosphate or Polyphosphate tests.
