There is a growing environmental and health concern associated with contamination by heavy metals. It has also been intensified due to an increase of the exposure to such pollutants as a result of industrial and technological growth. Therefore, it is necessary to remove heavy metals in contaminated water to eliminate the associated risks. This study focused on the removal of heavy metal ions using silica sulfuric acid (SSA). A comprehensive study was conducted to assess the effect of different factors on the adsorption by SSA as well as selectivity properties of the adsorbent, kinetic and thermodynamic studies of the adsorption process. A batch test was used to remove heavy metals from a multi-element solution containing Ni(II), Pb(II), Mn(II), Cu(II), and Cd(II). The results showed that removal rate reached its peak at pH, string time, and adsorbent amount equal to 8, 60 min, and 0.04 g/mL of solution, respectively. The removal efficiency of Ni²⁺, Cd²⁺, Mn²⁺ dropped by increasing the volume of solution and smoothed at 150 mL while the removal of Pb²⁺ and Cu²⁺ did not vary with the volume. The removal efficiency by SSA was decreased as Pb > >Mn > >Ni ≥ Cu > Cd. In general, SSA successfully removed heavy metals from contaminated water.

与重金属污染相关的环境和健康问题日益受到关注。由于工业和技术增长导致此类污染物暴露的增加，这种情况也加剧了。因此，有必要去除受污染水中的重金属，以消除相关风险。本研究的重点是使用二氧化硅硫酸 (SSA) 去除重金属离子。进行了一项综合研究，以评估不同因素对 SSA 吸附的影响以及吸附剂的选择性、吸附过程的动力学和热力学研究。使用批量测试从含有 Ni(II)、Pb(II)、Mn(II)、Cu(II) 和 Cd(II) 的多元素溶液中去除重金属。结果表明，去除率在 pH 值、字符串时间、和吸附剂的量分别等于 8、60 分钟和 0.04 g/mL 的溶液。Ni的去除效率²⁺、Cd ²⁺、Mn ²⁺随溶液体积的增加而下降并在150 mL 时平滑，而Pb ²⁺和Cu ²⁺的去除不随体积变化。SSA的去除效率随着Pb>>Mn>>Ni≥Cu>Cd而降低。总的来说，SSA 成功地从受污染的水中去除了重金属。
