To extend the life of the resin, reducing the impact of nh4 + ions on the adsorption of l-glutamic acid, often Xiulian selection d61 macroporous resin exchange macroporous resin mechanical strength is higher than the gel-type resin, this may be extended resin life, time to consider nh4 + ions and is

To extend the life span, reduced resin NH 4+ ion adsorption on L -glutamic acid, and the impact she often use large hole D 61 resin, resin due to the huge holes in the mechanical strength is higher than gel-type resin, resin that can be extended, and the life because of the introduction of the 61 ho

In order to lengthen the resin the service life, reduces NH4+ the ion pair L- glutanic acid adsorption the influence, Chang Xiulian selects the D61 pocket resin to carry on the exchange, because the big pass resin mechanical strength is higher than the gelatin resin, like this may lengthen the resin

To extend the life of resin, reducing the effect of NH4+ ion on adsorption of l-glutamic acid, Chang Xiulian use D61 macroporous resin for Exchange because of macroporous type resins have higher mechanical strength than gel type resins, thus extending the life of resin, and as the use of the D61 mac
