BARROZO, M.A.S.; OLIVEIRA, D.T.; SANCINETI, G.P.  and  RODRIGUES, M. V.. A study of the desorption isotherms of lentils. Braz. J. Chem. Eng. [online]. 2000, vol.17, n.1, pp.105-109. ISSN 1678-4383.

The aim of this work was to analyze the main equilibrium equations used for grains to find the best way to represent the equilibrium conditions between lentil and air. The experimental study was based on the static method using saturated salt solutions. We developed criteria for distinguish between some existing equations used for grains. To distinguishing between these equations we explored some nonlinearity measures. The results obtained showed that the Halsey modified equation was the best model in terms of nonsignificance for bias and nonlinearity measures.

Keywords : desorption; lentils; equilibrium equations.
