H₂S Loss through Nalophan™ Bags: Contributions of Adsorption and Diffusion

Table 4

Averaged data of the amount of H₂S adsorbed per surface unit (). The bag tested was without any film inside (B-no film) and with the film inside. The surface of the internal film sheet was equal to 1900 cm² (B- film 1900), 2580 cm² (B- film 2580), and 3520 cm² (B- film 3520), respectively. The data reported are the average of the results from three different tests performed at the same conditions.
