Green Synthesis and Characterization of Biosilica Produced from Sugarcane Waste Ash

Table 3

Physical-chemical properties of biomass ash and biosilica.

	SWA	Biosilica
pH	5.70	7.80
	—	5.29
CEC (meq 100 g)	—	4.25
Bulk density (g cm^−3)	1.41	0.708

CEC = cationic exchange capacity; = point of zero charge.
