Different procedures were carried out for the preparation and separation of the total alkaloids of Lolium temulentum. Loline has been identified as the major pyrrolizidine alkaloid of the seeds. The toxicity of the alcoholic ...
Novel thorium membrane sensors with anionic response based on trioctylphosphine oxide and toluate ionophores
(
Wiley-VCH Verlag
, 2008 , Article)
Two novel potentiometric polymeric membrane sensors for rapid and accurate determination of thorium are described. These are based on the use of trioctylphosphine oxide (TOPO) and thorium toluate (Th-TA) as ionophores ...
