It is easy to come across ludicrous articles and YouTube videos promising online side gigs that “pay $600 per day.” They typically describe things like setting up affiliate blogs. Now, these can bring in hundreds of dollars per day, but you don’t start to see those sums until you’ve put in thousands of hours of effort, research and unpaid work. W 铮? M

The decision on the question of public interest needs to be taken at the highest level. The decision must be taken by the editor, or the highest available authority in your news organisation. Even so, it may not be the right one, but where controversy is possible it is always wise for there to be a proper reflection on the issues and possible consequences. Q

产品名称:碳酸铈
分子式:Ce2(CO3)3
分子量:218.1396
CAS NO. :54451-25-1
外观性状:白色或无色粉末,易溶于酸,密闭保存。
用途:用于制造三元催化剂、铈盐中间体、硬质合金添加剂、陶瓷工业。
包装:纸板桶包装25、50公斤/件,编织袋包装25、50、500、1000公斤/件。
碳酸铈是白色或略带淡黄色结晶粉末,颜色随纯度变化而略有变化,属斜方晶系,难溶于水。将其水悬浮液煮沸,则水解生成碱式碳酸盐。在碱金属碳酸盐溶液中生成难溶的碳酸复盐Ce2(CO3)3?Na2CO3?2H2O。能和大多数酸反应生成相应的盐。在900℃加热时分解为CeO2。
碳酸铈的生产方法:溶剂萃取法以粗氢氧化铈为原料,分别用磷酸三丁酯-液态石蜡和二(2-乙基己基)磷酸-煤油作萃取剂提纯,得到氯化铈盐酸溶液。再用氨水中和,加入碳酸氢铵沉淀碳酸铈,沉淀经过滤、洗涤、离心、干燥后即为碳酸铈产品。
