High toxicity and bioaccumulation are the two major features that make mercury as the most dangerous heavy metal for the living organisms and mandates its removal from the contaminated water bodies. Keeping this in view, a new gelatin-based mesoporous hybrid material, with SiO₂ as the inorganic and gelatin as the biopolymeric component, was synthesized via the sol-gel process. The material was characterized by FTIR, SEM, SEM-EDS, TEM and BET studies. The synthesized hybrid material containing Gelatin/SiO₂, has high surface area of 675.92 m²g^-1. It was evaluated as an adsorbent of Hg²⁺ ions from their aqueous solutions. Parametric study of the factors affecting adsorption process was carried out to find the optimum adsorption conditions. Different kinetic and isotherms models were applied to the data obtained and adsorption was found to follow pseudo-second order kinetics and Langmuir isotherm model. The highest partition coefficient value of 7.13 mg g^-1 µM^-1 was obtained at the lowest initial Hg²⁺ ions concentration (50 ppm) studied alongwith an adsorption capacity of 43.85 mg/g while for the highest initial concentration of 225 ppm the respective values were 0.876 mg g^-1 µM^-1 and 105.075 mg/g. Cumulative adsorption capacity of the hybrid material from reusability studies in seven cycles was found to be 315.6 mg g.⁻¹

高毒性和生物蓄积性是汞的两个主要特征，使汞成为活生物体最危险的重金属，并要求将其从受污染的水体中清除。考虑到这一点，通过溶胶-凝胶法合成了一种新的基于明胶的介孔杂化材料，其中SiO ₂为无机材料，明胶为生物聚合物成分。通过FTIR，SEM，SEM - EDS，TEM和BET研究对材料进行了表征。合成的含有明胶/ SiO _2的杂化材料具有高表面积675.92m ² g ^-1。被评估为Hg ²⁺的吸附剂水溶液中的离子。对影响吸附过程的因素进行了参数研究，以找到最佳的吸附条件。不同的动力学和等温线模型应用于所获得的数据和吸附发现符合假-二级动力学和Langmuir等温模型。在研究的最低初始Hg ²⁺离子浓度（50 ppm）下获得最高分配系数值7.13 mg g ^-1 µM ^-1，吸附容量为43.85 mg / g，而对于最高初始浓度225 ppm则分别获得值为0.876 mg g ^-1 µM ^-1和105.075mg / g。通过七个循环的可重复使用性研究得出的杂化材料的累积吸附容量为315.6 mg g。^-1
