The Adsorption Of Trace Cobalt (Ⅱ) Nickel(Ⅱ) And Malachite Green From Waste Water By Using Eggshell Membrane

With the rapid development of science and technology，various heavy metaland other organic pollutants were discharged into the environment，causingincreasingly severe the soil and water problems．It is a common concerned topic ofthe effective governance and removal of pollutant．Therefore，it is particularlyimportant to research the method of the removal of heavy metal from contaminatedwater．We mainly studied on the effect of adsorption and adsorption conditions ofeggshell membrane (ESM) to the metal ions cobalt，nickel and malachite green．Onthe basis of this，the eggshell membrane (ESM) was applied to recycle the tracemetal ions in environmental water samples．The main works are summarized asfollows：1、The adsorption methods used for removal of cobalt，nickel and malachitegreen from aqueous solution both at home and abroad were introduced and theadsorption properties and trends of absorbent materials were summarized．It isemphatically introduced about the use of biological materials and the significanceof discussing eggshell membrane adsorption properties．2、The structures of the eggshell membrane (ESM) were characterized byscanning electron microscopy (SEM) and Fourier transform infrared spectroscopy(FT-IR)，and their adsorption performances to cobalt were researched．Weestablished a new method to adsorb cobalt with eggshell membrane (ESM)．Thesorbent eggshell membrane (ESM) was coupled with graphite furnace atomicabsorption spectrometry (GFAAS) and was applied to analysis of actual samples．3、The adsorption method by using eggshell membrane was combined with theflame atomic absorption spectrometry in this section．And we also discussed theadsorption behavior of nickel on egg shell membrane．A new method of eggshellmembrane (ESM) to recycle nickel was established and applied to the actual watersamples．4、The adsorption behavior of malachite green (MG) on egg shell membrane(ESM) was presented．The effect of pH，adsorbent dosage，adsorbent concentrationand contact time were performed by static testing．...
