RELATIONSHIP BETWEEN UNITS AND FORMING PECTINS ALGINATES, BIOADSORBENTES MATERIALS AND BOSORPTION OF CU (II)

Descripción del Articulo

The adsorbent capacity of biomasses pre-treated has been evaluated, containing pectin and alginate. The orange shells and lemon and the nopal palmets were dried and crushed, before being treated with NaOH to produce the demetoxilation of the pectin. For the reticulation of the polysaccharides they b...
