Table 1 Effect of cations on flocculating activity (n=3, mean ± SD)

From: Flocculating performance of a bioflocculant produced by Arthrobacter humicola in sewage waste water treatment

CATIONS FLOCCULATING ACTIVITY (%)
Fe3+ 57.90 ± 0.4a
Al3+ 65.30 ± 0.6b
K+ 33.10 ± 1.6c
Mg2+ 88.70 ± 0.9d
Na+ 41.70 ± 1.5e
Mn+ 75.70 ± 2.25f
Ca2+ 89.00 ± 0.7d
  1. Percentage flocculating activities with different superscripts are significantly different (p<0.05)
