Barakat, who is in his 40s, was arrested while trying to flee northern Lebanon to Turkey using a fake passport.
He is accused of recruiting young men from Tripoli to fight with IS in Syria and Iraq and of attacking Lebanese army units in the Sunni-majority city last year.
The army launched a security plan in April 2014 in an effort to stabilise Tripoli, which has seen deadly rounds of fighting between Sunnis who support the Syrian uprising and pro-Damascus regime Alawite residents.
Sunni gunmen in the city have often also clashed with the army.
In October 2014, 11 soldiers were killed when clashes erupted following the arrest of a Lebanese man accused of recruiting fighters for jihadist rebel groups in Syria.
