Cobalt skin dose resulting from short and repetitive contact with hard metals.
Contact Dermatitis 70(6) , 361-8, (2014) Many daily contacts with metallic items are short and repetitive, and result in metal release; material, sweat, friction and wear may all be important.To study cobalt release and skin deposition as a result of many short and repetitive contacts with two cobal... |

A spot test for detection of cobalt release - early experience and findings.
Contact Dermatitis 63(2) , 63-9, (2010) It is often difficult to establish clinical relevance of metal exposure in cobalt-allergic patients. Dermatologists and patients may incorrectly assume that many metallic items release cobalt at levels that may cause cobalt dermatitis. Cobalt-allergic patient... |

Metal ion binding to D-xylose isomerase from Streptomyces violaceoruber.
Biochem. J. 250(1) , 285-90, (1988) The binding of two activating cations, Co2+ and Mg2+, and of one inhibitory cation, Ca2+, to D-xylose isomerase from Streptomyces violaceoruber was investigated. Equilibrium-dialysis and spectrometric studies revealed that the enzyme binds 2 mol of Co2+/mol o... |

Substoichiometric determination of cobalt in crud.
Radioisotopes 34(4) , 201-6, (1985) A substoichiometric extraction method with nitroso-R salt (NRS) has been studied for the determination of trace Co in crud. The Co-NRS complex is extracted substoichiometrically into Capriquat-CHCl3 at pH 6.5-9.0 in 20 min of shaking time. The analytical resu... |

Column chromatographic pre-concentration of iron(III) in alloys and biological samples with 1-nitroso-2-naphthol-3,6-disulphonate and benzyldimethyltetradecylammonium-perchlorate adsorbent supported on naphthalene using atomic absorption spectrometry.
Analyst 115(9) , 1191-5, (1990) The solid ion-pair material produced from the reaction between benzyldimethyltetradecylammonium chloride (BDTA) and sodium perchlorate on naphthalene provides the basis for a simple, rapid and selective technique for pre-concentrating iron from up to 500 ml o... |

Determination of trace cadmium in waters by flame atomic absorption spectrophotometry after preconcentration with 1-nitroso-2-naphthol-3,6-disulfonic acid on Ambersorb 572.
Ann. Chim. 95(1-2) , 77-85, (2005) A procedure for the determination of trace amount of cadmium after adsorption of its 1-nitroso-2-naphthol-3,6-disulfonic acid chelate on Ambersorb 572 has been proposed. This chelate is adsorbed on the adsorbent in the pH range 3-8 from large volumes of aqueo... |
