我們把青霉素空盒中的硅膠干燥剂处理成变色硅膠,代替無水氯化鈣或濃硫酸等干燥剂,不仅节約了無水氯化鈣等干燥剂,克服了有时在市場上購买不到無水氯化鈣的困难,而且把以往当做廢物乱扔的青霉素盒中的硅膠也利用上了,现將其处理方法介紹如下。从青霉素盒中取出硅膠,讓它在空气中或置于篩孔較少的药篩上放在蒸汽水浴上,充分吸收水分,直至用数滴水滴于已吸收水分的硅膠上而極少爆制成碎粒为止,然后加入2—5%的氯化亚钴溶液,浸約5个小时。除去殘液后,于105℃的烘箱中烘到变成为藍色即 We put the penicillin empty box of silica gel desiccant into color silica gel, instead of anhydrous calcium chloride or concentrated sulfuric acid and other desiccants, not only saving desiccants such as anhydrous calcium chloride, to overcome the sometimes not available in the market To anhydrous calcium chloride difficulties, but also in the past as a litter of penicillin in the box of silica gel also used, and now its treatment methods are described below. Remove the silica gel from the penicillin cartridge and let it sit on a steam bath in the air or on a sieve with fewer meshes to fully absorb the water until it drops with a few drops of moisture-absorbed silica gel with minimal explosion Made of nibs, then add 2-5% cobaltous chloride solution, soaking for about 5 hours. After removing the raffinate, it was baked in an oven at 105 ° C until it became blue
