The involvement of a secondary solvent in the phase transfer process had only small effects on the particle size and distribution , zeta potential , and mobility of the nC ( 60 ) products but significantly influenced the capability of nC ( 60 ) to enhance the transport of 2 , 2 ' , 5 , 5 ' - polychlorinated biphenyl ( PCB ) in a saturated sandy soil column , regardless of whether the secondary solvent was water - miscible or non - water - miscible .
 Chemical: nC ( 60 ); Chemical: nC ( 60 ); Chemical: 2 , 2 ' , 5 , 5 ' - polychlorinated biphenyl; Chemical: PCB
