Acid modified diatomaceous earth - A sorbent material for thin layer chromatography

Ergül, Soner; Savaşcı, Şahin (Preston Publ Inc, 2008)

Natural diatomaceous earth (DE) is modified by flux calcination and refluxing with acid. To characterize natural DE, modified DE’s [flux calcinated (FC)DE and FCDE-I] and silica gel 60GF254 (Si-60GF254) are analyzed ...
Extraction of some transition metals with N,N-dibutyl-N '-benzoylthiourea into molten paraffin at 65 degrees C

Merdivan, Melek; Güngör, Ayla; Savaşcı, Şahin; Aygün, Rüveyde Sezer (Elsevier Science Bv, 2000)

The solid-liquid extraction behaviour of some transition metals (Cu(II), Co(II), Ni(II), Cd(II) and Pb(II)) by the use of N,N-dibutyl-N'-benzoylthiourea as an extractant in paraffin (58-60 degrees C) has been investigated ...
Thin-layer chromatographic specification and separation of cu1+, cu2+, ni2+, and co2+ cations

Savaşcı, Şahin; Akçay, Mehmet; Ergül, Soner (Oxford Univ Press Inc, 2010)

The M(PyDTC)2 (M: Cu, Co, or Ni) and CuPyDTC complexes, prepared by reactions of ammonium pyrrolidinedithiocarbamate with metal nitrates, are examined for qualitative analysis, speciation, and mutual separation using ...
