a kinetic spectrophotometric method for rapid measurement of thiocyanate in serum, urine and sewage water with no need for removed of interfering substances in described. the method is based on the inhibitory effect of thiocyanate on the oxidation of pyrogallol red by bromated and nitrite which is monitored at 467 nm. the variables affecting the rate of the reaction were investigated and the op...

Providing safe tap water while limiting the occurrence of disinfection by-products (DBPs) is probably one most challenging aspects environmental chemical engineering within urban cycle. In present work, an investigation about this challenge for real conditions a full-scale drinking treatment plant has been carried out. Five different and well-known technologies (four aeration procedures, coagul...

the structure of the nonaaquayttrium (iii) bromate, [y(h2o)9](bro3)3, at low temperature (100 k) has been studied by means of single-crystal x-ray diffraction. crystallography shows a hexagonal unit cell, space group p63/mmc (no. 194) with z = 2, a = b = 11.7104(11) å, c = 6.6259(5) å and v = 786.90(12) å3 at 100 k. the hydrated trivalent yttrium(iii) ion forms a tricapped trigonal prism, in wh...
