Synthesis of Low TENORM Zirconium Sulfate from ZrO(OH)<sub>2</sub> with Sulfuric Acid

Zirconium sulfate (ZS) has become one of the alternative chemical compounds for substituting traditional tannery substances using chromium(III) which was not environmentally friendly. The purpose of this research was to synthesize ZS from ZrO(OH)2 using H2SO4 with low Technologically Naturally Occur...
