Objectives
Clay PreparationGeneral protocol for 100% Bu3HdP+ Sodium montmorillinite(NaMT) exchange:
Preparation of 100% Bu3HdP+(NaMT) exchange: 2.0095 g Na-MT x (92 meqv/100 g Na-MT) x (1 mol Bu3HdP+/1000 meqv) x (100/100)% x (507.65 g Bu3HdP+/1 mol Bu3HdP+) = 0.9385 g Bu3HdP+
Preparation of 50% Bu3HdP+(NaMT) exchange: 2.0046 g Na-MT x (92 meqv/100 g Na-MT) x (1 mol Bu3HdP+/1000 meqv) x (50/100)% x (507.65 g Bu3HdP+/1 mol Bu3HdP+) = 0.4682 g Bu3HdP+
