Reductimetric determination of peroxydisulphate, hydrogen peroxide, sodium perborate, nitrate and nitrite in concentrated phosphoric acid medium with iron(II)

Direct current electrogenerated chemiluminescent microdetermination of peroxydisulfate in aqueous solution

“…In the meantime, several techniques have been reported for the determination of S2082" (14)(15)(16)(17)(18). For example, about 10"3 ( = mol L'1) S2082" was detected using alternating current polarography (14).…”

“…For example, about 10"3 ( = mol L'1) S2082" was detected using alternating current polarography (14). Reductimetric, potentiometric, and colorimetric methods were also developed (15,16). These techniques, however, are not applicable to microdetermination.…”

Fertilizers

“…Murty et al (144) presented a method for reductimetric determination of nitrate, nitrite, and other compounds in concentrated phosphoric acid with iron (II). The method was reported useful in the estimation of the NOcf content of fertilizers.…”
