It was aimed to quantify the Potassium adsorption to substrates with different proportions of vermiculite and peat, in addition to determining adsorption isotherms which would best fit the observed adsorption data, for contact periods of one and seven days. We carried out batch adsorption essays, using as an adsorbent media substrate prepared with different proportion of vermiculate and peat, and as adsorbate, solutions with concentrations of 0, 25, 50, 75 and 100 mg/L of K. The substrate that showed the highest adsorption capacity, then less leaching potential, was the one constituted with the largest amount of peat. The Freündlich’s isotherm best represents the K adsorption phenomenon in all the studied treatments.</p>}, number={Contínua}, journal={Revista Engenharia na Agricultura - REVENG}, author={Leal, Bruno de Paula and Thebaldi, Michael Silveira and Silva, Yasmin Fernandes and Pinto, Pâmela Rafanele França and Martins, Ivani Pose and Sales, Ronan Souza}, year={2023}, month={maio}, pages={51–63} }
