OBJECTIVES
PVOH 130K Prepared Hydrogel Samples
Preparations For Clay - Surfactant Exchanged Soils(Important Information and Notes About Clay)
(Such ions incldue: Al3+, Mg2+, Si2+, Li+, and Fe2+ or 3+,)
1.9999 g NaMT x (92 meqv/100 g NaMT) x (1 mol DMHXLBR/1000 meqv) x (110/100)% x (431.45 g DMHXLBR/1 mol DMHXLBR) = 0.8732 g DMHXLBR
(Repeat the entire process again in order to complete a 110% exchange with laponite clay and surfactant DMHXLBR)
2.9672 g NaMT x (55 meqv/100 g NaMT) x (1 mol DMHXLBR/1000 meqv) x (110/100)% x (431.45 g DMHXLBR/1 mol DMHXLBR) = 0.7745 g DMHXLBR (Repeat the entire process again in order to complete a 50% exchange with NaMT clay and surfactant, Bu3HdP+)
2.0001 g NaMT x (92 meqv/100 g NaMT) x (1 mol Bu3HdP+/1000 meqv) x (50/100)% x (507.65 g Bu3HdP+/1 mol Bu3HdP+) = 0.4671 g Bu3HdP+
Notes
# Laponite # Sodium Montmorrillonite (NaMT)
# Tributyl hexadecyl phosphonium bromide (Bu3HdP+) # Methyl 16 bromohexadecanoate (DMHXLBR)
