J Ind Eng Chem, 20: 42764285. Esta temperatura es mayor para el quitosano en comparacin con el QC, probablemente debido a que el quitosano presenta mayor ndice de cristalinidad evidenciado en los difractogramas DRX y en los anlisis calorimtricos diferenciales de barrido (DTG). [Links], 12. Esta diferencia de la cristalinidad se refleja en la estabilidad trmica, puesto que un compuesto, al poseer mayor cristalinidad, su estructura molecular ser ms rgida y por consiguiente se necesita mayor energa para que se pueda descomponer. Es el adsorbente ms utilizado, ya que la mayora de sus propiedades qumicas (por ejemplo, grupos de superficie) y fsicas (por ejemplo, distribucin del tamao de los poros y rea de la superficie) se pueden ajustar de acuerdo con lo que se necesite. The Langmuir and Freundlich models were used to fit the experimental data (Fig. In terms of proximity adsorption, the functional acid sites and the condensed and rigid monoliths with tunable periodic scaffolds of the cubic mesocages are useful in providing easy-to-use removal assays for organic compounds and reusable adsorbents without any mesostructural damage, even under chemical treatment for a number of repeated cycles [100]. [Links], 41 Zulkifli F, Ali N, Yusof MSM, et al (2017). Each adsorbent has its own characteristics such as porosity, pore structure and nature of its adsorbing surfaces. This can occur because of physical forces or by chemical bonds. Since 1860, phenol has been in production, with its basic use as an antiseptic.

Ambas micropartculas de quitosano se caracterizaron utilizando distintas tcnicas como la espectroscopa infrarroja con transformadas de Fourier (FTIR), difraccin de rayos X (DRX), anlisis termogravimtrico (TGA), anlisis termogravimtrico diferencial (DTG) y microscopa electrnica de barrido (SEM). In another study, the extent of adsorption of 2,4-dichlorophenol was found to be a function of pH. The results show maximum adsorption capacity( qm) of the pesticide on adsorbents (ACs) prepared from corn cob, olive kernel, soya stalks and rapeseed stalks at values 7.9x 10_2,12.3 x 10_2, 11.6 x 10_2 and 18.9 x 10_2 mmol/L, respectively.
