--------------I-also-tr3Ed-more--experimentG-involving TYPE 2 surrogate waste.
I adjusted the pH of the waste to 10.5 and tried to solidified
it. The best result obtained was a gell. I also tried the
same thing to surrogate waste TYPE 4 with the same results. I
tried to minimize the amount of energy input for mixing the
waste. The theory here is that oxygen may inhibit
polymerization, so I decided to hand mix two (2)
se3idificatio.^.s, a type 2(pH 10.5) and a type 4(pH 10.5)
surrogate. These solidifications have obtained the best gell
of all the variations tried (these gells are very firm).

I ordered copper sulfate to attempt solidification with the
derakane resin; it's possible the compound that the copper is
in might be inhibiting the polymerization. I have ordered
another polymer that is more reactive than the current polymer
being used for this testing program. Early indications show
that TYPE 4 surroaate waste can be solidified in this new
polymer. I have been working on optimizing the loading ratio
(waste to binder) for TYPE 4 surrogate waste. The following
experiments have been performed:

Sample "A° set up rock hard in a very few minutes, this waste
had a pH adjustment of 10.5. All the samples after "A" have no
pH adjustment. Sample "B" has set up but not rock hard.
Sample "C" a little better results than "B". Sample "D"
results are the same as "C". Sample "E" set rock hard. I can
only assume that the maximum waste to binder loading will be
greater than 1.5/1 but less than 2/1. Type 2 surrogate waste
solidification is promising but there still maybe the problem
of copper concentration.
