The average and multicomparisons of BET and Langmuir surfaces.

Variable	Newman-Keuls test; homogenous groups,
	5% aerocelluloses	9% aerocelluloses	11% aerocelluloses
single (m^2/g)	120.61 (A)	77.61 (B)	97.09 (AB)
(m^2/g)	124.42 (A)	80.01 (B)	100.17 (AB)
(m^2/g)	160.42 (A)	103.13 (B)	129.19 (AB)

Note: single: surface area determined by BET method at single point ; : surface area determined by BET method; : surface area determined by Langmuir method; A, B, and C: groups in multicomparisons.
