McIlvaine buffer_help

[G.S. Bhat]

Hi
 
I need some information on preparation of  McIlvaine
buffer. For my experiment I need 0.1 M  McIlvaine buffer of pH 6.0 but the
composition is 0.2M dibasic sodium phosphate  and 0.1M citric acid. How
can I prepare this buffer? As per my knowledge both components should
be same concentration while preparing buffers.So  any one knows about
this  please guide me
