Although not considered poisonous and with natural occurrence, Zn contamination is mainly related to anthropic actions. This research aim was to develop, from crambe wastes, adsorbents with high adsorption capacity of Zn²⁺. The crambe biomass was modified with H₂O₂, H₂SO₄ and NaOH 0.1 mol L⁻¹, resulting in four crambe-based adsorbents: C. in natura (unmodified), C. H₂O₂, C. H₂SO₄ and C. NaOH. These were studied by determination of their chemical components, SEM, FTIR, pH_PZC, thermal stability (by TG/DTG curves), SSA, pore volume and pore diameter (by BET and BJH). Adsorption studies were also carried out to evaluate its Zn removal capacity. Evaluations were taken on adsorbent dose and the influence of the pH, as well as studies on adsorption kinetics and equilibrium. These results were evaluated by pseudo-first order, pseudo-second order, Elovich, intraparticle diffusion, Langmuir, Freundlich, Dubinin-Radushkevich and Sips (linear and nonlinear models). Results show that the crambe-based adsorbents may have functional groups such as hydroxyls, amides, carbonyls and carboxylates, which may be responsible for the Zn²⁺adsorption. The materials have heterogeneous structure, allowing the occurrence of mono and multilayer adsorption of Zn. The finest results point out the occurrence of mono and multilayer of Zn²⁺ (evidenced by Sips-nonlinear model), with an increase in Q_sat of 72% (C. H₂O₂), 22% (C. H₂SO₄) and 80% (C. NaOH). The developed crambe adsorbents have low cost of production (since the raw material is until now a solid waste) and have high removal ratio of Zn²⁺ from waters, being a promising technology.

尽管不被认为是有毒的且自然发生的，但锌污染主要与人类行为有关。这项研究的目的是从蛤develop废料中开发具有高Zn ²⁺吸附能力的吸附剂。用H ₂ O ₂，H ₂ SO ₄和NaOH 0.1 mol L ^-1改性克拉姆生物质，得到四种基于克拉姆伯的吸附剂：自然界中的C. （未改性），C.H ₂ O ₂，C.H ₂ SO ₄和C. NaOH。通过确定其化学成分，SEM，FTIR，pH _{PZC来研究这些}，热稳定性（通过TG / DTG曲线），SSA，孔体积和孔径（通过BET和BJH）。还进行了吸附研究以评估其锌去除能力。对吸附剂剂量和pH值的影响进行了评估，并对吸附动力学和平衡进行了研究。通过伪一阶，伪二阶，Elovich，粒子内扩散，Langmuir，Freundlich，Dubinin-Radushkevich和Sips（线性和非线性模型）评估了这些结果。结果表明，基于克拉姆贝的吸附剂可能具有官能团，例如羟基，酰胺，羰基和羧酸盐，这可能是造成Zn ^{2+的原因。}吸附。该材料具有非均质结构，允许发生锌的单层和多层吸附。最好的结果指出了Zn ²⁺的单层和多层存在（通过Sips非线性模型证明），Q _sat的增加分别为72％（C.H ₂ O ₂），22％（C.H ₂ SO）。₄）和80％（C. NaOH）。发达的克拉姆布吸附剂生产成本低（因为至今原料仍是固体废物），并且从水中去除Zn ^2+的比率很高，这是一种很有前途的技术。
