Abstract

The aim of this research is to investigate the effect of K⁺ on the vaterite CaCO₃ formation using the steamed ammonia liquid waste as the calcium source. The obtained products were characterized by powder X-ray diffraction (XRPD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and laser particle size analysis (LPSA). The results show that K⁺ has an effect on the particle size, morphology, agglomeration, content, and yield of vaterite CaCO₃. The effects of K⁺ on the crystallization and growth of vaterite are different under the different Ca²⁺: CO2–3 ratio system. Mechanistic analysis shows that K⁺, by reducing the pH range of the reaction process and decreasing the ionic activity of the reaction system, promotes the vaterite formation. This study can provide a reference for the synthesis of vaterite using industrial waste.

以蒸氨废液为钙源，K离子对水晶石CaCO3形成的影响

本研究以蒸氨废液为钙源，探讨K+对水晶石CaCO3形成的影响。采用粉末x射线衍射（XRPD）、扫描电镜（SEM）、傅里叶变换红外光谱（FTIR）和激光粒度分析（LPSA）对所得产物进行了表征。结果表明，K+对钒石CaCO3的粒径、形貌、团聚、含量和产率均有影响。不同Ca2+: CO2-3比体系下，K+对水晶石结晶和生长的影响是不同的。机理分析表明，K+通过降低反应过程的pH范围和降低反应体系的离子活度，促进了水晶石的形成。本研究可为利用工业废渣合成水晶石提供参考。

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
