OFFLINE

Today I had to attend a disciplinary meeting regarding facebook posts. The posts in question were done via my mobile phone and the content not related to my job. My profile is set as private and only accesible by my 'friends'. A print out of my wall posts has been obtained and as I have none of my work colleagues on my friends list this must have been done by using someone outside of the company.

I assured my employers (who I do not list as employers on my profile) that the comments made were not related to my job or its employees but this seemed to fall on deaf ears.

The conclusion of this meeting was that I would hear a decision regarding possible dismissal within the next couple of days. Is this possible grounds for gross misconduct and subsequent dismissal?

you should probably discuss this with an attorney who specializes in labor law in your state or if under a union contract contact your steward or business agent.
some states have "at will" employment laws which allows firing without cause.
however those laws do not supercede federal laws against unfair firing such as  http://www.nlrb.gov/news/settlement-reached-case-involving-discharge-facebook-comments
