Need help with mechanism for Dehydration of Secondary Alcohol

[Really Lost]

Hi I was wondering if someone could provide a link or post/attach the full reaction mechanism (including all steps) of the dehydration of a secondary alcohol, say 2-butanol including all the end products (is there a hydrogen ion left at the end?) My instructior showed the reaction with H2PO as the catalyst but I think I copied it wrong and I haven't been able to find it online.

 

Thanks.

H3PO4 is a more likely bet.
