In order to study the effect of inorganic salt additives on surface tension a sodium dodecylbenzene sulfonate (SDBS) solution, mixed system six common additives, NaCl, CaCl2, AlCl3, Na2SO4, Na2CO3, and NaHCO3, SDBS was measured, effects types, surfactant concentrations solution were studied. On this basis, three salts, CaCl2 selected, their critical micelle concentration (CMC) The experimental ...

This study discusses strength deterioration during the curing process of fly ash geopolymer and the use of CaSO4·2H2O (gypsum) as a deterioration remedy when the ash was synthesized using a 10M NaOH and Na-silicate solution. The strength decline was mainly due to the widespread formation of nanometer-sized cracks that were related to excessive Na and Si concentrations at an early age. Use of 2 ...

The phase behaviour of two model multi-component salt-water mixtures (NaCl-KCl-H2O and NaCl-Na2SO4-H2O) was investigated for the application supercritical water desalination (SCWD). experimental investigation a two-step procedure starting with qualitative analysis followed by quantitative measurements. experiments served as screening step to visually inspect behaviour. results NaCl-KCl-H2O, sho...

salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. this study was conducted to determine the ion exchanges in halocnemum strobilaceum and halostachys caspica in saline conditions. the...

The study presents kinetics of degradation and mineralization an anti-epileptic drug Lamotrigine (LAM) in the aqueous matrix by electrochemical advanced oxidation process (EAOP) on Ti/DSA (Ta2O5-Ir2O5) Stainless Steel (SS) anodes using sodium sulphate as supporting electrolyte. On both anodes, kinetic behaviour was pseudo-first-order for well LAM. anode, maximum LAM 75.42% observed at associate...
