For studying an opportunity of quantitative definition Сo²+, Cu²+, Ni²+ in the method of solid,phase spectrophotometry (SSР) with preliminary concentrating natural diatomite Сеlite 545 modified (the 1,(2,pyridilazo),2,naphtol) (PAN) is applied. Adsorption Сo²+, Cu²+, Ni²+ on modified diatomite is investigated. Optimum time of preliminary concentrating Сo²+, 10 min., Cu²+, 5 min. for their subsequent quantitative definition is established. Limits of definition Сo²+( 1*10,⁶, 1*10,⁵mol/l), Cu²+( 2*10,⁶, 2*10,⁵ mol/l) are found by method SSP.
