Mass spectrometric studies of the vapours over solid lead oxide in a flow of gaseous arsenic and antimony trioxides were conducted. The following ions of the ternary oxides were detected: Pb3As2O6(+), Pb3AsO4(+), PbAs2O4(+), PbAsO2(+), PbSb2O4(+), and PbSbO2(+). The origin of these species produced by the ionisation and/or fragmentation of ternary gaseous oxides is discussed. The PbAs2O4 specie...

The ultraviolet absorption spectrum of vitamin A with itsmaximum near 328 m,. was described nearly 20 years ago (Morton & Heilbron, 1928a, b). The intensity of absorption shown at that wave length by a fish-liver oil or concentrate was conveniently expressed in terms of E "lo 328 m,u. (Gillam & Morton, 1929), and this magnitude was early seen to afford a guide to potency. If a number of fish-li...

We have studied the refining effects of refining agents and ultraviolet transmitting property of soda lime glass, for the purpose of developing ultraviolet transmitting glass with soda lime glass composition which is one of an inexpensive glasses. It was found that for glass that requires ultraviolet transmitting property, antimony oxide, which is commonly used as a refining agent, cannot be us...

Received: 20 September 2014 Received in revised form: 20 October 2014 Accepted: 25 October 2014 Published online: 31 March 2015 Printed: 31 March 2015 Segregation of antimony trioxide (ATO) from back‐coated textiles was studied for two types of textile samples: A (ATO‐Hexabromocyclododecane) and B (ATO‐Decabromodiphenyl ether). Samples A was found to lose 5.3, 12, 28 and 39 %wt:wt of the amount...
