Introduction

Analysis of the core content of the standard

Technical indicators	Liquid product requirements	Solid product requirements	Detection method
Alumina (Al₂O₃)	≥6.0%	≥28.0%	Zinc chloride titration method (arbitration)
Basicity	30.0-95.0%		Acid-base neutralization method
Lead (Pb) content	≤0.001%		Atomic absorption spectrometry

Technology evolution analysis

Compared with the 2008 version, this standard has the following major improvements:

New heavy metal detection items such as cadmium, mercury and chromium
Arsenic determination upgraded to atomic fluorescence method
Lead detection switched to flame atomic absorption method
Density determination item deleted

Detailed explanation of key detection methods

Determination of alumina content

Arbitration method steps: After the sample is depolymerized with nitric acid, excess EDTA solution is added at pH 3 and back-titrated with zinc chloride standard solution. Calculation formula:

w₁ = [(V₀-V)×c×M×10^-3/2]/(m×V₁/V_A)×100

Parallel determination tolerance: liquid ≤0.1%, solid ≤0.2%

Implementation suggestions

Raw material control: Select bauxite with low heavy metal content
Process monitoring: Focus on monitoring basicity and pH value
Packaging and storage: Liquid products must be frost-proof, solids must be moisture-proof
Safety protection: Wear acid and alkali resistant gloves during operation
