Treatment of Textile Waste Water with Organoclay
In this study a sample of bentonite obtained from Semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. BET analysis showed that the modification increased its surface significantly. The prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from Ekbatan textile company. Adsorption was studied in ...
متن کاملSurface Properties of Natural Calcite Filler Treated with Stearic Acid
In order to obtain hydrophobic material, the water suspension of natural limestone with the high content of calcite (>95 %), was treated with different amounts (0.5-4 %) of stearic acid dissolved in chloroform. Thermal analysis showed that at lower initial concentrations of stearic acid (up to 2 %), surfactant molecules are chemisorbed on calcite surface, while at higher initial concentrations ...
متن کاملInfluence of stearic acid coating of the NaCl surface on the reactivity with NO2 under humidity.
In the atmosphere, sea salt aerosols, containing mainly NaCl, can accumulate fatty acids and undergo heterogeneous chemistry with atmospheric nitrogen oxides. The effect of stearic acid (SA) coating on the reactivity of the NaCl(100) surface with NO2 under humidity was studied by atomic force microscopy (AFM), Raman mapping and time-of-flight secondary ion mass spectrometry (ToF-SIMS) to highli...
متن کاملCure Characteristics and Physico-mechanical Properties of the Stearic Acid Surface of Modified Calcium Carbonate Reinforcement NR/SBR Compounds
Calcium carbonate is a cheap and readily available filler used in rubber industry. This material is not compatible with rubber matrix, so many researchers have tried to modify its surface with various materials in order to increase its hydrophobicity and improve compatibility with the rubber matrix. In this effort, surface modification of calcium carbonate was carried out by 1.5%, 3% and 4% ste...
