Worldwide research groups are searching for anticancer compounds, many of them are organometalic complexes having platinum group metals as their active centers. Most commonly used cytostatics from this group are cisplatin, carboplatin and oxaliplatin. Cisplatin was used fot the first time in 1978, from this time many platinum derivatives were created. In this review we present biological proper...

Platinum Metals Rev., 2006, 50, (1), 38–45 The Ninth Grove Fuel Cell Symposium and exhibition was held at the prestigious Queen Elizabeth II Conference Centre in Westminster, London, from 4th to 6th October 2005. This biannual event is now the largest fuel cell gathering in Europe, this one attracting 480 delegates from 38 countries (1, 2). Some 54 papers were presented, and 186 posters were di...

Abstract In this research, a recycling process for palladium using “dry aqua regia,” which consists of iron(III) chloride–potassium chloride, was proposed. Palladium dissolved in and the recovered by leaching with potassium chloride solution added ammonium nitric acid. almost completely 3 h at 600 K, recovery ratio up to 80%. addition, dissolution coexistence platinum platinum-palladium alloy r...

The main standard method for gold karat determination is the cupellation method. However, this method is not sufficiently accurate to determine gold karat in the presence of insoluble Platinum–Group Metals (PGMs), such as Ir, Ru, and Rh. In this study, for the first time, a complementary method that can be used coupled with the reference cupellation method is presented for the high...

Worldwide usage of platinum group metals is increasing, prompting new recovery technologies. Resting cells of Desulfovibrio desulfuricans reduced soluble Pd2+ to elemental, cell-bound Pd0 supported by pyruvate, formate, or H2 as the electron donor without biochemical cofactors. Pd reduction was O2 insensitive, opening the way for recycling and recovery of Pd under oxic conditions.
