Ammonia nitrogen, consisting of un-ionized ammonia and ammonium, is a key parameter for
studying the nitrogen cycle and indicating water quality. The measurement of these …

A large number of ex situ sampling techniques have been used traditionally to investigate
the impact and fate of pollutants in soil, sediment and waters. However, the distribution and …

The agarose hydrogel has been increasingly used as a diffusive layer in diffusive gradients
in thin films (DGT) measurements. However its diffusive characteristics have not been …

Abstract Ammonium (NH 4+) and ammonia (NH 3) in aquatic ecosystems are of great
interest to environmental scientists because they can be used to study the nitrogen cycle …

There is a lack of the understanding of the transfer of phosphate (PO 4-P), ammonium (NH 4-
N) and nitrate (NO 3-N) at the millimeter scale in sediments related to internal loadings in the …

This study reports two new holder configurations that can be used in the diffusive gradients
in thin films (DGT) technique, including a dual-mode holder and a new flat-type holder. The …

A new diffusive gradients in thin films technique (ZrO-AT DGT) with zirconium oxide, A-62
MP and T-42H resins containing in a single binding gel was developed for simultaneous …

Estuarine ecosystems have very high ecological and economic value, and also act as a
buffer for coastal oceans by processing nutrient inputs from terrestrial sources. However …

Abstract Evaluation of in situ capping with biochar (BC) to control ammonia nitrogen (NH 4+-
N) release from the sediments of Baiyangdian Lake, the largest freshwater lake in northern …

A modified diffusive gradients in thin films (DGT) technique uses both a mixed binding layer
(PrCH and A520E resins for NH 4-N and NO 3-N, respectively) and multiple binding layers …
