TY - JOUR A2 - 沃尔佩，莫里吉奥AU - 侯赛因，纳迪亚AU - Alwan的所在地，萨拉姆AU - Alshamsi，哈桑AU - Sahib的，易卜拉欣PY - 2020 DA - 2020年3月16日TI - 绿色S-的合成和N共掺杂碳纳米球和应用从水溶液SP的Pb（II）的吸附 - 9068358 VL - 2020 AB - 在本文中，含硫和氮的共掺杂的碳纳米球的绿色和简便合成（CNS）从提取物制备 玫瑰茄L请直接水热法。最后，硫碳纳米球（CNS）用作吸附剂，以除去铅⁺²离子从由于来自CN的和N-的CN S-CN的高表面积的水溶液。将合成的纳米球是由傅立叶检查变换红外（FTIR）光谱法，X射线衍射（XRD），场发射扫描电子显微镜，透射电子显微镜（TEM），和氮吸附 - 脱附等温线。The results show spherical shapes have a particle size of up to 65 nm with a high surface area capable of absorbing lead ions efficiently. Additionally, the factors affecting the process of adsorption that include equilibrium time, temperature, pH solution, ionic intensity, and adsorbent dose were studied. The equilibrium removal efficiency was studied employing Langmuir, Freundlich, and Temkin isotherm forms. The kinetic data were analyzed with two different kinetic models, and both apply to the adsorption process depending on the values of correlation coefficients. The thermodynamic parameters including Gibbs free energy (Δ G度），标准焓变（Δ H度），和标准熵变化（Δ 小号°）分别计算吸附过程。SN - 1687-806X UR - https://doi.org/10.1155/2020/9068358 DO - 10.1155 /九百○六万八千三百五十八分之二千○二十零JF - 国际期刊化学工程PB - Hindawi出版KW - ER -
