1微波炉再生硅胶磷肥分析中常用硅胶作干燥剂,以恒重坩埚,保存样品,保持天平和药剂的干燥等。硅胶作干燥剂使用一段时间会吸湿失效,变色硅胶颜色会由蓝变红。硅胶再生传统法费时,费电,可采用微波炉再生硅胶,即将硅胶放入玻璃或陶瓷器皿中,一般不要铺得太厚,放入微波炉中2～3min,中火,如果是变色硅胶就会由粉红色变为蓝色,如果是非变色型硅胶,会变得比较透明。
1 Microwave Regenerative Silicone Phosphate analysis commonly used in silica gel as a desiccant to constant weight crucible, save the sample, to keep the balance and pharmaceutical drying. Silica gel for desiccant use for a period of time will hygroscopic failure, discoloration silica gel color from blue to red. Regenerate the traditional method of silica gel fee, electricity, microwave regenerative silicone can be used, about to put silica into glass or ceramic utensils, generally do not shop too thick, into the microwave 2 ~ 3min, the fire, if it is discolored by silica gel Pink to blue, if non-discolored silicone, will become more transparent.
