Figure 6From: Effect of organic matter on estuarine flocculation: a laboratory study using montmorillonite, humic acid, xanthan gum, guar gum and natural estuarine flocs Schematic diagram showing the effect of various organic matter (GG: guar gum; XG xanthan gum; HA: humic acid) on the flocculation of aqueous montmorillonite suspension at low (~0 psu) and high (~7-17.5 psu) salinity.
