Ammonia Diffusion through Nalophan Double Bags: Effect of Concentration Gradient Reduction

Table 1

Experimental data relevant to NH₃ diffusion over time in Nalophan bags: the inner double bags (DB_in 6000–2580) have = 6000 cm³ and = 2580 cm², the outer double bags (DB_out 6000–5280) have = 6000 cm³ and = 5280 cm², and the single bag is with = 6000 cm³ and = 2580 cm².
