“…Yet they have not been isolated without ligands, nor converted to larger cluster forms. Aqueous Cr 3+ ‐clusters mediate glucose metabolism; while excess Cr 3+ damages DNA . Different Cr 3+ clusters exhibit different oxidization rates to biotoxic Cr 6+ .…”

This study is dedicated to the memory of Leone Spiccia, who would have loved to see the chromium Keggin ion finally come to fruition.Abstract: Aqueous metal-oxo clusters without organic ligands (including polyoxometalates and group 13 polycations) are useful for energy, environmental and biomolecular applications. While ligands stabilize clusters of different elements, such as open-shell transition metals, they inhibit reactivity and solubility. Therefore a grand challenge is to conceive and execute synthetic strategies to isolate metal-oxo clusters of any composition, without ligation. Here we crystallize and structurally characterize a Cr 3+ dodecamer Keggin ion without organic ligation.[a]

“…Selain itu, sifat Hg yang pada umumnya berikatan dengan mineral dan mudah berikatan dengan klorin, sulfur, oksigen dan karbon, mengakibatkan secara alami logam Hg akan dijumpai di alam meski dalam jumlah yang kecil (Suyanto et al, 2010). Tingginya kosentrasi logam berat dekat mulut muara diduga kuat juga disebabkan oleh sifat logam berat yang memiliki tingkat kelarutan tinggi, susah didegradasi dan mudah terakumulasi di kolom perairan (Kotas dan Stasicka, 2000;Pawlikowski et al, 2006;Biswas et al, 2017).…”

The purposes of this study were to determine the water quality, concentration and distribution of Hg in the surface water of Banyuasin river estuary. This research was conducted in June 2016 with 26 sampling stations. Measurement of in situ water quality was done using Conductivity Temperature Depth (CTD) multiparameter profiler while Hg metal was measured using Atomic Absorption Spectroscopy (AAS). The data obtained was interpolated by Inverse Distance Weighted (IDW) and then mapped spatially. The results showed that in general the water quality in Banyuasin river estuary still meets the seawater quality standards for marine biota based on KepMenLH no. 51 in 2004. The concentration of Hg in Banyuasin river estuary ranges from 0.001-0.032 mg/L with a distribution pattern that generally increases towards the ocean. The Hg concentration at the Banyuasin river estuary is on the maximum limit and exceeds the quality standard for marine biota.

“…8,9 For the online monitoring demand, electrochemical detection technology is widely used because of its high sensitivity, low cost, high-speed detection, miniaturization, easy integration, and convenient application. [10][11][12] An electrochemical detection system consists of a working electrode (WE), reference electrode (RE), and counter electrode (CE). The RE provides a stable reference potential for the electrochemical detection system to ensure that the potentials of the WE are accurate.…”
