Effects of Metal Ions on Viscosity of Aqueous Sodium Carboxylmethycellulose Solution and Development of Dropping Ball Method on Viscosity

Viscosity is an important and fundamental physical property of fluids as it is physically expressed in transportation phenomenon such as momentum of flow. Dynamic properties of solutions are commonly influenced by their static microscopic structures; however, these structures are difficult to deduce from their dynamic properties.
Sodium carboxylmethylcellulose (CMC) is a polymer substance popularly used in food and cosmetics, as well as in the agricultural, chemical and biological engineering fields due to its relatively high viscosity in aqueous solution and environmentally friendly nature.1 Several researchers have investigated the properties of CMC and have published in this and other journals. Those studies have revealed the effectiveness of CMC as an additive, a substrate, a blending material, a stabilizer, a binder, a scaffold material, etc.
