Ether of carboxymethylcellulose-based picric acid(CMC-PA) was prepared from carboxymethylcellulose(CMC) and picric acid(PA) by the mild reactive conditions of acidylation with chloric.The strcture of CMC-PA was characterized by FTIR,Element analysis,XRD and CPMAS13C NMR.Influences of reaction conditions,such as reaction temperature,reaction time,ratio of CMC to PA and amount of pyridine,were studied by mass fraction of nitrogen.Result showed that the synthetical conditions were obtained as ratio of CMC to PA 2 : 1 (by weight),amount of pyridine 50 mL,reaction temperature 85°C and reaction time 4 hours.The adsorption property of CMC-PA to creatinine was studied under simulated biological human body conditons.The kinetic and isothermal curve were given. Results showed that adsorption amount reached an equilibrium value after 10 hours,and the maximum adsorption amount was 1.75mg/g.Equilibrium data of creatinine fit well with Freundich equation,indicating that the adsorption was mainly chemical monolayer adsorption .The Freundich indx(1/n) was less than 1,which implied that the adsorption was preferential process.

Surfactant Templates

Nano-rods hydroxyapatite (HA) was synthesized by hydrothermal method using Ca(NO3)2·4H2O and H3PO4as precursors and cationic surfactant (CTAB) as a template. The effect of pH value and reaction temperature on the phase and morphology of HA were investigated. HA samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was found that high pH values resulted in high purity of HA. HA morphology changed from irregular round shape to nano-rod shape with the increase of the reaction temperature from 80°C to 120°C. The prepared HA was utilized as adsorbent to remove copper ion from aqueous solution. The adsorption results showed that nano-rod HA had a rapid Cu2+adsorption rate and good removal efficiency (>99%).

Silk Fabrics

Carbon nanotube is a new type of nanoscale materials, which has excellent adsorption property and electrical conductivity. In this paper, silk fabrics were antistatic modified by adsorption of carbon nanotube. The results indicate that the optimum modified conditions are summed up as follows: quality ratio of carbon nanotube and silk fabric is 1:5, pH value is 4, reaction temperature is 95°C and reaction time is 1.5 h. The antistatic property of silk fabric which modified by carbon nanotube is obviously improved.

Initial Concentration

Tobermorite nano-scale powder was synthesized from potassium feldspar ore from Henan province Lushi country in China. In the present research work, its adsorption property to Cd2+ was studied. The factors of adsorption such as pH values, traction time, initial concentration, and temperature were studied. The adsorption equation was curvefitted by the Langmuir and Freundlich adsorption isotherm and the thermodynamics adsorption was analyzed. By the orthogonal experiment and single-factor experiment of the adsorption, the optimized conditions of the adsorption for Cd2+ were achieved: the reaction temperature is 40°C, the reaction time is 20 min, the initial concentration of aqueous solution is 20 mg•L-1 and pH value is 6.0. Under these conditions the adsorption efficiency of Cd2+ can reach 99.89%. The orthogonal experimental results show that the order of effect on adsorption efficiency was the initial concentration, pH value, reaction temperature, reaction time. In different temperatures, the results show that isothermal Langmuir equation can describe the isothermal adsorption characteristics of Cd2+ on tobermorite. Thermodynamic parameters can be drawn: the G was negative and with increasing temperature H increased, so the adsorption process is a spontaneous reaction to the heat.
