Sorption isotherm models used for furcellaran.

Model	Equation
GAB (Van der Berg and Bruin, 1981)	${\mathrm{X}}_{\mathrm{e}}=\frac{\mathrm{a}\mathrm{b}\mathrm{c}{a}_{\mathrm{w}}}{\left(1-\mathrm{c}{a}_{\mathrm{w}}\right)\left(1-\mathrm{c}{a}_{\mathrm{w}}+\mathrm{b}\mathrm{c}{a}_{\mathrm{w}}\right)}$
Caurie (Castillo et al., 2003)	${\mathrm{X}}_{\mathrm{e}}=\exp \left(\mathrm{a}+\mathrm{b}{a}_{\mathrm{w}}\right)$
Henderson-Thompson (Thompson et al., 1968)	${\mathrm{X}}_{\mathrm{e}}={\left[\frac{\ln \left(1-a_{\mathrm{w}}\right)}{-\mathrm{a}\left(\mathrm{T}+\mathrm{c}\right)}\right]}^{1/\mathrm{b}}$
Modified Oswin (Chen, 2000)	${\mathrm{X}}_{\mathrm{e}}=\left(\mathrm{a}-\mathrm{b}\mathrm{T}\right){\left(\frac{a_{\mathrm{w}}}{{1-a}_{\mathrm{w}}}\right)}^{\mathrm{c}}$
Peleg (Peleg, 1993)	${\mathrm{X}}_{\mathrm{e}}=\mathrm{a}{\left(a_{\mathrm{w}}\right)}^{\mathrm{b}}+\mathrm{c}{\left(a_{\mathrm{w}}\right)}^{\mathrm{d}}$
Smith (Smith, 1947)	${\mathrm{X}}_{\mathrm{e}}=\mathrm{a}-\mathrm{b}\left(\ln \left(1-a_{\mathrm{w}}\right)\right)$
