This study was aimed at determining the optimum condition for desorption of cadmium loaded carbon nanotubes (cCNTs) for re-adsorption of the same metal ion. Two independent parameters (contact time and HCl concentrations) were subjected to statistical optimization by face centered central composite design (FCCCD). Maximum desorption cCNT was achieved under the optimized conditions of pH 1.40 and 130 min contact time. The coefficient of determination (R2) of the developed model was found to be 0.988, indicating the fitness of the experimental and predicted responses. Following the desorption experiments, the efficiency of re-adsorption of Cd2+ by the CNT was 61.08%. The reduced re-adsorption capacity of CNT could be linked to modification of its sorption sites based on acid desorption process.

Carbon-cobalt nanostructures 1 and 2 were prepared by pyrolysis of the cisdichlorobis(1,10-phenanthroline-N,N')-cobalt(II) complex 3 in the absence or presence of anthracene respectively. DFT calculation was used to estimate ligand dissociation energy of cobalt complex, the energy cost for the formation of cobalt particles which catalyze the formation of carbon nanostructures. FE-SEM analysis indicates that 1 and 2 contain 3D nanostructure hierarchical porous graphitic carbons HPCGs wrapping cobalt particles in spheres and rods, with mesopores and macropores ranging from 10-100 nm. TEM analysis indicated that nanostructures 1 and 2 consist of graphite layers as well as single wall and bamboo multiple wall carbon nanotubes. Crystalline cobalt catalyst nanoparticles were found wrapped in ordered graphene layers and also at the tips of the bamboo-shaped disordered multiwall carbon nanotubes. TEM also showed porous surfaces. Both nanostructures 1 and 2 were used as adsorbents to uptake malachite green dye (MG) from aqueous solution. Adsorption isotherms of MG by adsorbents 1 and 2 were fitted in terms of Langmuir, Freundlich, Temkin, and D-R models. The adsorption capacity of 2 (492 mg/g) was higher than that of 1 (200 mg/g). Thermodynamic adsorption studies indicated that the sorption process was spontaneous and exothermic. A pseudo-first order model has been adopted to describe the kinetics of the adsorption process as well as the activated thermodynamic parameters. Column kinetic adsorption of MG by 2 was best fitted by the Thomas model. The column capacity was found to be 64 mg. The adsorbent can be regenerated and proved efficient for three consecutive cycles.

分别在无蒽或有蒽的情况下，对顺二氯(1,10-菲罗啉-N,N′)-钴(II)配合物3进行热解制备了碳-钴纳米结构1和2。采用DFT计算方法估计钴配合物的配体解离能，即钴颗粒催化碳纳米结构形成的能量成本。FE-SEM分析表明，1和2含有三维纳米结构层叠多孔石墨碳HPCGs包裹钴颗粒呈球形和棒状，具有10 ~ 100 nm的中孔和大孔。TEM分析表明，纳米结构1和2由石墨层、单壁碳纳米管和竹多壁碳纳米管组成。晶体钴催化剂纳米颗粒被包裹在有序的石墨烯层中，也被包裹在竹状无序多壁碳纳米管的尖端。TEM还显示了多孔表面。采用纳米结构1和纳米结构2作为吸附剂吸附孔雀石绿染料(MG)。采用Langmuir、Freundlich、Temkin和D-R模型拟合吸附剂1和2对MG的吸附等温线。2的吸附量(492 mg/g)高于1的吸附量(200 mg/g)。热力学吸附研究表明，吸附过程是自发的、放热的。采用拟一阶模型来描述吸附过程动力学和活化热力学参数。Thomas模型最适合于MG对2的柱动力学吸附。柱容量为64毫克。该吸附剂可再生，连续循环三次，效果良好。A R T I C L E H I S T O R Y收稿日期:2016年11月1日修稿日期:2017年04月02日收稿日期:2017年04月07日DOI: 10.2174/2210681207666170509145222
