Adsorbate-adsorbent behaviour/affinities in a wastewater batch reactions! e.g. among the cellulosic/fibrous based nano-metallic (silver, zinc or iron etc.) composites (Adsorebents) v/s toxic metals such as Hg, Cr, Ni, Cd, Co, Pb etc.
Dear Attarad Ali,
There are few things needs to be consider for this as follows,
1- First factor in the attachment of metallic NPs to the polymer surface depends on their value of zeta-potential. Agglutinated NPs with poor surface charge can't be adsorbed on polymer surface. So please see the zeta-potential of NPs at first.
2- Second factor is molecular weight of polymers. Usually, polymers with low molecular weight like CMC facilitated more surface attachment.
3- Next comes physico-chemical parameters of NPs (Crystillite parameters, NPs size, shape, bandgap energy etc.)
4- Moreover, doping of polymers is difficult bcz, amorphous and crystalline materials are tough to doped. Doping means that no phase impurities in XRD and only crystal defects which can be traced using XPS and Raman spect. I suggest that Polymer/NPs composite is better term for understanding.
pH, solvent nature and concentration of NPs/Polymer also very important for surface attachment.
