Effect of monovalent, divalent and trivalent ions on the grinding
For pure bentonite, elevating the pulp pH led to a reduction in the zeta potential, likely attributed to the adsorption of OH − ions onto the surfaces of bentonite. Nevertheless, with the presence of Al 3+, Mg 2+, or K + ions, the zeta potential of bentonite remained largely unaffected by the pH increase up to pH 8.

absorption capacity of fluff pulp could be increased using some strategies. Among others, a few studies have used minerals and non-wood pulps in order to manufacture fluff pulp. In fact, the addition of minerals, such as bentonite, into the fluff pulp can increase the absorption capacity of fluff pulp due to its superabsorbent properties [8].
