TL;DR: Recent advances in technology, such as the development of suitable chromatographic and capillary electrophoresis separation techniques, should help to elucidate some of the more pertinent questions regarding inositol phosphates in the natural environment.

TL;DR: For example, in this article, the authors used the enzyme-based approach to classify water-extractable molybdate-unreactive organic phosphorus (MUP) from five Australian pasture soils into compounds that could be hydrolysed by (i) alkaline phosphomonoesterase (comprising labile orthophosphate monoesters, such as sugar phosphates), (ii) a combination of phosphodiesterase and alkaline PHs), (iii) phytase (including inositol hexakisphosphate) and (iv

TL;DR: This review aims to rationalise the findings of the many 'optimised' molybdenum blue methods in the literature in terms of the underlying polyoxometallate chemistry and offers suggestions for the further enhancement of this time-honoured analytical reaction.

TL;DR: The aim of this review is to provide a detailed overview of the μPADs that have been developed for the determination of important water quality parameters, such as nutrients, metals and organic contaminants, in a range of waters.

TL;DR: A low-cost disposable colorimetric microfluidic paper-based analytical device (μPAD) was developed and successfully applied to the determination of nitrate and nitrite in both synthetic and natural water samples.
