Removal of malachite green using carboxymethyl cellulose-g-polyacrylamide/montmorillonite nanocomposite hydrogel - ScienceDirect
Here, q e is the equilibrium adsorption capacity (mg/g), q m is the maximum adsorption capacity (mg/g), k L is the Langmuir adsorption constant that represents the binding energy, k F and n are the Freundlich model constants, b T (kJ/mol) and A
Nonionic surfactant and temperature effects on the viscosity of hydrophobically modified hydroxyethyl cellulose (HMHEC) solutions are investigated experimentally. Weak shear thickening at intermediate shear rates takes place for HMHEC at
SNF Australia - Water Soluble Polymers
Water soluble polymers cover a wide range of highly varied families of products of natural or synthetic origin,and have numerous uses. Among these families, synthetic polymers, and more particularly coagulants and flocculants,are used mainly for

Interaction between a Nonionic Surfactant and a Hydrophobically Modified 2-Hydroxyethyl Cellulose | The Journal of Physical Chemistry B
Interaction between the nonionic surfactant Tergitol 15-S-7 and hydrophobically modified 2-hydroxyethyl cellulose (HMHEC) was studied rheologically in a semidilute regime of HMHEC. The low-shear viscosity of HMHEC was increased with addition of
