Atomic absorption inhibition titration of orthophosphate and polyphosphates

Fertilizers

“…A rapid, simple, and accurate atomic absorption inhibition titration method for ortho-, pyro-, tri-, tetra-, and hexaphosphates was developed by Crawford et al (28). Total consumption and premix slot burners were studied and gas flow rates were optimized.…”

Determination of sulfate by flame emission inhibition titration

“…Titration methods based on inhibition effects of anions on flame photometric signals of metals were introduced by Torok (1) and have since been applied to several determinations (2)(3)(4). A method for the simultaneous determination of silicate, phosphate, and sulfate utilizing magnesium atomic absorption has also been reported (5).…”
