Anodic dissolution and cathodic deposition of 20 transition metals in acidic solutions in liquid ammonia has been surveyed. The early transition metal elements Ti, Zr, V, Nb, MO and W form high oxidation-state insoluble amido complexes during anodic oxidation. Soluble ammines of normal metal oxidati

A new method for the determination of inorganic salts of chloride and bromide is described. The method is based on the facts that iodine forms complexes with the anions and that these complexes absorb strongly in the UV region. The molar absorptivities of I2Br- at 265 nm and I2Cl- at 245 nm were cal
An assay capable of detecting tens-of-picomole quantities of choline and acetylcholine in milliliter volumes of a physiological salt solution has been developed. Silica column chromatography was used to bind and separate IO-3000 pmol ['4C]choline and [?Z]acetylcholine standards made up in 3 ml of a
