读过四川邛崃农业科等有关制备胡敏酸钠的报导后(原载本刊1959年第6期——编者),我们觉得,胡敏酸存在的形态是多种多样的,只用一种方法来制备胡敏酸,不完全就会满意,而且,也不一定对每一具体情况都能适合。因此,我们根据邱林院士用来比较研究土壤腐植质组成的方法,补充地作出了几个方法,供生产上制备胡敏酸钠的参考。制备胡敏酸钠以前,取风干泥炭,研末,过100
After reading the report on preparation of sodium hypochlorite in Sichuan Agricultural Science and Technology Department (originally published in Journal of China Science Press, No. 6, 1959-), we think that the humic acid exists in a variety of forms with only one Method to prepare humic acid, incomplete will be satisfied, and, may not necessarily fit every specific situation. Therefore, based on the methods used by academician Qiu Lin to comparatively study the composition of soil humus, several methods were supplemented for reference for the preparation of sodium huminate for production. Preparation of sodium huminate before taking peat air dried, the end of 100
