Subject: safe disposal of NaOH in THF

style='tab-interval:.5in'>

I have a colleague who needs to dispose of NaOH (about 1M) in 50:50 THF/water which has turned orange after 1-2 years.  Any thoughts?  For example will a peroxide test be accurate in the presence of the NaOH?  Would it be safe to neutralize the NaOH? 

Thanks,
