Dye Adsorption by Posidonia oceanica from Aqueous Solutions

2 Dye Adsorption by Posidonia oceanica from Aqueous Solutions 

Sample Treatment Langmuir (R -value) Freundlich (R -value) 

Both Langmuir and Freundlich adsorption equihbrium isotherm models were used to determine the adsorption equilibrium of the samples treated using different types of plasma [56-57]. The correlation coefficient, R -value was determined from the model curve and the results are shown in Table 12.5. 

Superhydrophilic surface property (9 5° within 1 second of droplet contact) was achieved at high-energy argon-plasma (180 kj) and low-energy
