Development of a generalized adsorption isotherm model at solid-liquid interface: A novel approach

摘要: Abstract The adsorption at solid-liquid interface is mostly described through the Langmuir and Freundlich isotherm models. However, these models sometimes give an ambiguous estimation of model parameters by ignoring assumptions originally considered for development. In present study, generalized was developed analyzing plot isolating zones. initial linear zone segregated combined Langmuir- based applied nonlinear zone. effect other mechanisms apart from also addressed higher equilibrium concentrations. An system analyzed. provides qmax, KL R2 as 52.425 mg/g, 0.149 L/mg 0.989, whereas, proposed Ki, Kaeq, n1, Kom, n2 are 6.355 L/g, 40.437 mg/g, 0.090 L/mg, 1.430, 1.00 × 10− 6, 0.5 0.997. can be to demonstrate systems.
