Perchlorate Determination by Conductometric Titration
Perchlorate determination in tap water sample and blank value with standard in deionized water
The application note describes the perchlorate determination in tap water sample and Blank value with standard ammonium perchlorate in deionized water using conductometric titration method.
Background:
Perchlorate is both a naturally occurring and manmade chemical used in the production of rocket fuel, missiles, pyrotechnics, fireworks, flares and explosives. Its widespread release into the environment through ground water, soils and plants, and making its way up the food chain is primarily associated with defense, military operations and aerospace programs.
Out of the four perchlorate compounds produced in the greatest quantities, ammonium perchlorate alone accounts for about 90 % of all perchlorate manufactured. EPA has announced it a “likely human carcinogen” because of its potential to cause endocrine system and reproductive problems. Thus, its high usage in several applications, perchlorate determination is of prime importance.
Perchlorate in the sample is determined by titrating against Tetrabutylammonium hydroxide (TBAH). The equivalence point EQP is determined conductometrically.
Reaction:
NH4ClO4 + TBAH --------> NH4OH + TBAClO4
