GB/T 4698.8-1996 《Sponge titanium，titanium and titanium alloys--Determination of aluminium content--Separation with sodium hydroxide-EDTA complexometric titration method》 Related products

GB/T 4698.8-1996 For sponge titanium, titanium and titanium alloys, the alkali separation-EDTA complexation Titrimetric method is used to determine the aluminum content. It is suitable for samples of such metal materials. After alkali separation, the aluminum content is determined by the complexation reaction of EDTA and aluminum. The standard specifies the required instruments, such as Burette, etc., and specifies various reagents. Detailed description of the Sample Handling steps, including the alkali separation process, removal of interfering elements, and then the EDTA complexation titration operation, such as titrant addition, reaction condition control and endpoint determination. With this standard, the aluminum content can be accurately determined, which can help the mass control and performance optimization of related products.
