(HPC) with common formulae GaMoxW12 - xO40-5 . Purpose: using these complexes for increasing sensitivity of gallium determination. The condition of separation of gallium HPC from isopolycomlexes and HPC P, Si, Ge have been found. Stability and formation of complexes with common formulae GaMoxW12 - xO40-5 were investigated with help of extraction method. The methods of direct and indirect determination of gallium in various objects were worked out using the extraction concentration. Methods are recommended for gallium determination in alloys and semiconducts. Application: analytical chemistry of gallium.
