摘要

采用旋转盘反应器(SDR)在液-液体系中合成沉淀碳酸钙颗粒，并进行了成功的试验。提议的特别提款权反应器由一个转速为每分钟4000 - 16000转的旋转盘组成。由于高速旋转的圆盘产生了强烈的能量耗散，所提出的SDR导致了较高的局部过饱和比。转速越高，生成的碳酸钙纳米颗粒平均粒径越小，文石含量越高。在15000转/分的转速下，可以得到粒径约为975 nm的碳酸钙纳米颗粒。此外，通过将磁盘速度从4000转增加到15,000转，文石含量从10%增加到95%。

High local supersaturation formation for precipitated calcium carbonate synthesis by applying a rotating disk reactor

A spinning disk reactor (SDR) was applied and tested successfully for precipitated calcium carbonate particles synthesis in liquid–liquid system which is poorly understood in literature. The proposed SDR reactor consists of a spinning disk rotating at 4000–16,000 rpm. The proposed SDR resulted in a high local supersaturation ratio due to the intense energy dissipation produced by a high-speed spinning disk. The higher rotational speed of SDR produces calcium carbonate nanoparticles with smaller mean particle sizes and higher aragonite content. At the rotating speed of 15,000 rpm, precipitated calcium carbonate nanoparticles with a size of around 975 nm were produced. In addition, aragonite content increased from 10 to 95 wt% by increasing disk speed from 4000 to 15,000 rpm.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
