Detection and determination of nitrate and nitrite: a review.

A review of the strategies employed to facilitate the detection, determination and monitoring of nitrate and/or nitrite is presented. A concise survey of the literature covering 180 reports submitted over the past decade has been compiled and the relevant analytical parameters (methodology, matrix, detection limits, range, etc.) tabulated. The various advantages/disadvantages and limitations of the various techniques have been exposed such that the applicability of a technique developed for one type of matrix can be meaningfully assessed before attempting to transfer the technology to another.
