Neste estudo, determinaramse em colunas de solos os fatores de retardamento, coeficientes dispersivodifusivos e curvas de efluente, assim como a concentração residente dos íons potássio, sódio, cálcio e magnésio presentes na água residuária da lavagem e despolpa de frutos do cafeeiro conilon. Inicialmente, as colunas foram interligadas a frascos de Mariotte contendo água destilada, durante período suficiente para passar dois volumes de poros e, em seguida, a frascos contendo a água residuária. As concentrações relativas das amostras oriundas do efluente, correspondentes aos respectivos volumes de poros, foram utilizadas a fim de obter as curvas experimentais de efluente para sódio, potássio, cálcio e magnésio. Modelos matemáticos para concentração no fluxo foram ajustados aos pontos amostrais das curvas de efluente, permitindo, assim, obter os valores dos fatores de retardamento e coeficientes dispersivodifusivos para os íons. Para o latossolo, os fatores de retardamento foram superiores àqueles encontrados para o aluvial e argissolo. Por outro lado, os coeficientes dispersivodifusivos não apresentaram tendência entre os três solos. As concentrações residentes dos solutos apresentaram a ordem de grandeza: aluvial < argissol < latossolo.This study was carried out to determine the retardation factors, diffusivedispersive coefficients and effluent curves, as well as the resident concentration of potassium, sodium, calcium and magnesium ions found in the wastewater from washing and pulping of the conilon coffee cherries. Initially, the columns were interlinked to Mariotte flasks containing distilled water, over period enough to pass two pore volumes of the soil, and then being linked to flasks containing this wastewater. The relative concentrations of the samples from the effluent, corresponding to the respective pore volumes, were used in order to obtain the experimental effluent curves for sodium, potassium, calcium and magnesium. Mathematical models for concentration of the flow were adjusted to the sample points of the effluent curves, therefore allowing it to obtain the values of either retardation factors and dispersivediffusive coefficients for those íons. For Latosol, the retardation factors were superior to those found for the Alluvial and Argisol. However, the dispersivediffusive coefficients presented no tendency among those three soils. The resident solute concentrations showed the following magnitude order: Alluvial < Argisol < Latosol
