GRAVIMETRIC DETERMINATION OF NICKEL WITH CYCLOHEXYLIDINE-AMMONIUM-2-AMINOC YCLOHEXY LIDINE- 1-CYCLOHEXENE-1-DITHIOCARBOXYLATE
Cyclohexylidine-ammonium-2-aminocyclohexyline-l-cyclohexee-l- dithiocarboxylate (CCCD) is employed for the gravimetric determination of Ni (II). In neutral or ammoniacal solutions, the metal forms a violet precipitate with the reagent which can be weighed as Ni (C13H18NS2)a2f ter drying at 115 - 120?C Using this procedure, the nickel content of steel samples can also be determined accurate...

متن کاملGravimetric determination of pipette errors
In chemical measurements (for instance in titrimetric analysis) it is very important to precisely measure amount of liquid, the measurement is performed with use of various measuring vessels. Presently laboratories use all kinds of glass measuring vessels like: beakers, flasks, etc., for measurement of bigger volumes of liquid, and in case of small volumes glass pipettes. Glass pipettes have be...
متن کاملGravimetric Determination of Soil Organic Matter
Studies were carried out to evaluate a gravimetric method for the determination of soil organic matter by the mass loss at 300C. The gravimetric method was compared with Walkley-Black, using several brazilian soils with variable chemical and physical properties. Gravimetric method was positively correlated with Walkley-Black method with the following linear regression equation: y = 3.72x + 0.29...
متن کاملThe Conjugation of a - Naphthylacetic Acid in vivo
Aromatic and arylalkyl carboxylic acids commonly undergo metabolic conjugation prior to excretion, the conjugating agent being either a carbohydrate or an amino acid. Among mammalian species the carbohydrate is usually glucuronic acid, but in the case of the amino acids, one or more of glycine, glutamine or taurine may be used, and the particular pattern of amino acid conjugation depends upon t...
