ecletica-480	Vaghetti, Julio Cesar Pacheco; Brasil, Jorge de Lima; Costa, Tania Maria Haas; Lima, Éder Cláudio; Benvenutti, Edilson Valmir	Influence of the synthesis conditions on the characteristics and metal adsorption properties of the 3-(1,4-phenylenediamine)propylsilica xerogel	2005	7	.pdf	application/pdf	3405	212	62	The presence of the organic component of the hybrid materials can be by confirmed by the elemental CHN analysis, which showed 0.6 and 0.5 mmol of organic groups per gram of xerogel for samples A and B respectively. Thus, considering the surface organic coverage, the best sample is the A, that has 89 % of the total organics (0.6 mmol g-1, Table 1), in opened pores, corresponding to 0.53 mmol of available organic groups per gram of xerogel, while sample B presents only 65 % of total organics (0.5 mmol g-1, Table 1) in opened pores, corresponding to only 0.33 mmol of available organic groups per gram of xerogel (Table 2).	cache/ecletica-480.pdf	txt/ecletica-480.txt
