Readiness of lignosulfonate adsorption onto montmorillonite

Five types of lignosulfonate (LS) for example the sodium LS (SLS), ammonium LS (ALS), calcium LS (CLS) and magnesium LS (MLS) were compared through the term of functional group and adsorption capability. Main goal of this research was to study the readiness of LS adsorption onto montmorillonite. Fou...
