Determination of metals in natural waters by inductively coupled plasma optical emission spectroscopy after preconcentration on silica sequentially coated with layers of polyhexamethylene guanidinium and sulphonated nitrosonaphthols
A series of complexing adsorbents is prepared by coating silica particles with linear polyhexamethylene guanidinium (PHMG) chloride followed by saturation with a number of sulphonated nitrosonaphthols reagents electrostatically ...
Structure of bis(2-Thiobarbiturate)Tris (2,2-Bipyridyl)Nickel(II) Hexahydrate
The [Ni(Bipy) 3 ](Htba) 2 ·6H 2 O (I) complex (Bipy is 2,2′-bipyridyl, H 2 tba is 2-thiobarbituric acid) is synthesized and its structure is determined by single crystal XRD (cif-file CCDC No. 1836529). The crystals of I ...
