Effect of Organic Additives on Synthesis and Characterization of Nano Crystalline StrontiumMalonate

Abstract

A basic study was carried out to synthesis of nano crystalline strontium malonate and to understand the crystallization of strontium malonate without and with addition of sodium dodecyl sulfate surfactant (SDS) and poly ethylene glycol (PEG). Induction time was measured under different supersaturations ranging from 2.6 to 4.3. This is the time elapsed between the achievement of supersaturation and the appearance of a solid phase. The results show that, the induction time decreases exponentially with increasing the Supersaturation. On the other hand, the induction time is decreased with addition of SDS and PEG. Interestingly, with addition of the SDS and PEG, the agglomerated samples are investigated by using Scanning Electron Microscopy (SEM) investigation, the crystalline sizes of the formed crystals without and with SDS and PEG are 244 nm, 222 nm and 121 nm, respectively.
