Issledovana kinetika reakcii vzaimodeystviya hlorida nikelya s ditionitom natriya v vodnom rastvore, protekayuschey s obrazovaniem metallicheskogo nikelya za schet vosstanovleniya kationov nikelya. Obnaruzheno, chto parallel'no s osnovnoy stadiey processa imeyut mesto reakcii razlozheniya ditionita natriya s obrazovaniem v kachestve konechnyh produktov sul'fita, tiosul'fata i sul'fida. Na osnovanii analiza dannyh eksperimenta i literatury predlozhen stehiometricheskiy mehanizm processa. S ispol'zovaniem metoda matematicheskogo modelirovaniya reshena obratnaya kineticheskaya zadacha po opredeleniyu konstant skorosti otdel'nyh stadiy processa. Sravnenie eksperimental'nyh i raschetnyh kineticheskih zavisimostey pozvolilo sdelat' vyvod ob adekvatnosti predlozhennoy matematicheskoy modeli eksperimental'nym dannym.
