微波对某些物质既不产生反射也不被吸收,而是顺利通过,对能吸收的物质具有深层加热作用。自Shawky·H·Tadras[1]利用微波恒重BaSO4沉淀,重量法测定了三甘氨酸硫酸盐的含量以来,至今未见其用于磷肥工业的分析。尝试用玻璃砂芯坩埚过滤BaSO4沉淀,微波加热测定了磷肥工业中几种原料和产品中全硫含量。实验表明,这个设想是可行的,尤其适合批量样品的快速测定。
Microwave does not produce any reflection or absorption of certain substances, but passes smoothly, which has a deep heating effect on substances that can be absorbed. Since Shawky H. Tadras [1] using microwave constant BaSO4 precipitation, gravimetric determination of triglycine sulfate content has so far been no analysis for the phosphate fertilizer industry. Try glass sand core crucible filter BaSO4 precipitation, microwave heating was measured in the phosphate fertilizer industry, several raw materials and products of total sulfur content. Experiments show that this idea is feasible, especially for rapid determination of bulk samples.
