Abstract The adsorptive interaction of 2-aminophenol (2 - AP), 2 - nitrophenol (2 - NP), 4 - aminophenol (4 - AP) and 4 -nitrophenol (4 - NP) with manganese and nickel ferrocyanides have been studied at neutral (pH 7.01 ± 0.01) and at thermal (T° 30 ±1^oC) conditions. The progress of adsorption was followed spectrophotometrically by measuring the absorbance of amino acids solution at their corresponding . The Langmuir type of adsorption is followed in the concentration range of 10^-4 to 10^-5 mol/L of substituted phenol solutions. Nickel ferrocyanide was found to have greater adsorption ability in comparison to manganese ferrocy anide with all four substituted phenol adsorbates. 4 -Nitrophenol and 2 - aminophenol was found to have greater and lesser affinity, respectively with both metal ferrocyanides studied.
