用草酸洗蓝墨水污渍已载入各种家庭大全、生活手册等书中,在有些化学教材中也把它作为草酸用途之一而叙述。故而已成为常识而家喻户晓。但实际情况如何?我们对此做了一点调查与实验。曾经在市面上出售过的蓝墨水有二种,一种是早先在市场上出售的,以可溶性普鲁士蓝KFe[Fe(CN)_6]为主要成份的普蓝墨水。另一种是目前市场上出售的,以墨水蓝(结构如下)为主要成份的蓝黑墨水,如北京牌蓝黑
Washing blue ink stains with oxalic acid has been included in various family books, lifestyle manuals, and other books. It is also described as one of the oxalic acid uses in some chemistry textbooks. Therefore, it has become a household name and has become a household name. But what is the actual situation? We have done some research and experiments on this. There are two kinds of blue inks that have been sold on the market. One is the Prussian blue ink which was previously sold on the market and contains soluble Prussian blue KFe [Fe(CN)_6] as its main component. The other is a blue-black ink that is currently sold on the market, with ink blue (structured below) as the main ingredient, such as Beijing Brand Blue Black
