In recent years, instrumental techniques have gained prominence for their speed and precision. Ion chromatography, for instance, separates and quantifies ions based on their affinity to a resin within a chromatographic column. The sulfate ions are eluted and detected, typically by conductivity or UV detection after reaction with a reagent that enhances their detectability. The area under the peak in the chromatograph is proportional to the concentration of sulfate, which can then be translated to TiO2 content through appropriate calculations.

 Fourth, since the sulfate required for the production of the present invention is provided by the acid leaching slag itself, the mass fraction of the SO/- contained in the acid leaching slag is 15% or more, and the nanometer is prepared by using the acid leaching residue as the zinc and sulfate raw material of the lithopone. Lide powder products not only realize the resource utilization of acid leaching slag, but also turn waste into treasure, and treat and improve the acidic soil of acid leaching residue to purify the environment. Low production costs and simple operation. The metathesis reaction is carried out in a low-density ammonia system (the metathesis reactant is dissolved in recovered ammonia water), and the crystal nucleus formed is smaller. It is non-toxic and safe. The ammonia solution after synthesis and separation is returned to the leaching. There is no waste water in the whole production process. The produced waste residue meets the national solid waste discharge standard for efflux, conforms to the national industrial policy, and is an environmentally friendly “green” type process.
