Copper(II)-neocuproine as colour reagent for some biologically active thiols: Spectrophotometric determination of cysteine, penicillamine, glutathione, and 6-mercaptopurine
A new direct spectrophotometric method is described for determination of μg/ml concentrations of four biologically important thiols: cysteine, penicillamine, glutathione, and 6-mercaptopurine. TheExpand
New spot-test for cyanide ion and cyanogen gas.
A new, rapid and simple spot test has been developed for detection of both cyanide ion and cyanogen gas. The cyanogen gas must first be converted into cyanide ion by reaction with sodium hydroxide.Expand
Micro-and submicro-scale iodimetric determination of antimony (III) in antibilharzial compounds by use of amplification reactions.
Simple, rapid and highly sensitive iodimetric amplification methods are described for the micro- and submicro-determination of antimony(III) in antibilharzial compounds. The methods are based onExpand
Iodometric microdetermination of hydrazines by amplification reactions.
Two new, simple, rapid, and accurate iodometric amplification methods are described for the micro and submicro determination of hydrazine. The first depends on oxidation with a chloroform solution ofExpand
Iodometric submicro determination of α-amino-alcohols by an amplification reaction
Abstract New methods are described for the iodometric submicro determination of α-aminoalcohols possessing primary, secondary or tertiary amino-groups which involve 6-, 12-, and 18-fold amplificationExpand
Micro and submicro iodometric determination of arsenite and sulphite ions by amplification reactions.
Two methods are described for the micro and submicro iodometric determination of arsenite and sulphite ions involving 3- and 6-fold amplification reactions, respectively. The arsenite method is basedExpand
Microdetermination of arsenale and arsenite ions by using an amplification reaction with iodate resp. Iodine
ZusammenfassungEin einfaches und genaues Verfahren mit 12- bzw. 14facher Vervielfachung wird beschrieben. Die Arsenatbestimmung beruht auf der Reaktion mit Calciumjodat und jodometrischer TitrationExpand
New iodometric methods for the microdetermination of arsenic in organic compounds.
New methods are described for the iodometric microdetermination of arsenic in organic compounds after wet digestion or oxygen flask combustion. After evaporation of the arsenic solution to drynessExpand
Iodometric microdetermination of phosphorus in organic compounds
Abstract Two methods are described for the iodometric microdetermination of phosphorus in organic compounds. These methods depend on combustion by the oxygen flask, absorption of the combustionExpand
Iodometric microdetermination of phosphorus in organophosphorus compounds containing nitrogen, sulfur and halogens
Abstract A new general method is described for the iodometric microdetermination of phosphorus in organic compounds after combustion by the oxygen flask and absorption of the combustion products inExpand
