Platinum, palladium and rhodium of the raw feeds extracted and separated with a new sulfoxide extractant (MSO)were studied in the paper. The pilot test results showed that the percentage extractions are more than 99% for platinum and palladium in Pt-Pd feed, and the percentage strippings are 100% and 99.2% with HCl and ammonia, respectively. The ratio of palladium to platinum is 0.0016 in stripping platinum solution, and the ratio of platinum to palladium is 0.0020 in stripping palladium solution. The percentage extraction of platinum is 99% in Pt-Rh feed, and the percentage stripping is 100%.The ratio of rhodium to platinum is 0.0002 in stripping platinum solution. Therefore, platinum, palladium, and rhodium feeds are separated effectively with MSO.

科学技术与社会是科学技术哲学的一个重要分支,科学技术与社会的发展存在着协同进化的关系,即两者之间存在着相互联系、相互作用、共同发展的关系。对于信息技术外包而言,它属于高新技术,它存在太多的问题和拥有巨大的潜力,是值得我们去研究的,同时它也是属于科学技术与社会研究的范围。信息技术外包给企业带来了机会,节约了成本,提高了效率,但是由于川渝两地科技意识、社会条件、哲学发展等种种的限制,致使信息技术外包没
