PROBLEM TO BE SOLVED: To provide a monoclonal antibody specifically recognizing trivalent chromium obtained by the reduction of hexavalent chromium for the quantitative determination and detection of hexavalent chromium as an environment polluting substance and provide an immunological method using the monoclonal antibody.;SOLUTION: The monoclonal antibody is produced by bonding a trivalent chromium complex with a carrier such as a protein and using the product as an antigen. Trivalent chromium obtained by reducing hexavalent chromium is determined and detected as a complex with the monoclonal antibody to determine the hexavalent chromium.;COPYRIGHT: (C)2007,JPO&INPIT
