In these reports, the obtaining of HA has been done from precursors, either tricalcium phosphate, Ca3 (PO4)2 (Rivera et al, 1999) or phosphoric acid, H3PO4 (Balazsi et al, 2007; Lee & Oh, 2003).
Si se compara con otros biomateriales que han sido usados para la remocion de Pb(II) como el aserrin modificado con H3PO4 80,64mg/g (Ghasemiet al.,2014), avellana 128,18mg/g (Yuet al.,2013), almendra 8,08mg/g (Pehlivanet al.,2009), cascara de banano 2,18mg/g (Anwar et al.,2010), y cascara de naranja sulfurada 248,628mg/g (Lianget al., 2011) todos estos trabajos son reportados a temperatura ambiente (25-30[grados]C), se establece que los materiales usados en el presente estudio presentan un alto potencial para la remocion de metales en solucion acuosa.
According to the procedure of Baydar and Ulger (1998) for detecting GA3, methanol-water (30:70) adjusted to 3.0 pH with 0.1 M H3PO4 as mobile phase and the elutant was scanned at 208 nm; for IAA, 35% methanol prepared in 0.1 M acetic acid was used as mobile phase and reading wave length was 265 nm; and for ABA, 55% methanol in 0.1 M acetic acid and 280 nm were used as mobile phase and reading wavelength respectively.
Chemical activation process is a one-step method with the activating agents such as zinc chloride (ZnCl2), potassium hydroxide (KOH) and phosphoric acid (H3PO4) is mixed into the raw material and the end product is washed to remove the excess chemicals [6].
Effects of different chemical modifications on the adsorbent properties including different alkalis saponification (NaOH NH4OH and Ca(OH)2) and different acids (C6H6O7H2O H2C2O4 and H3PO4) modification after saponification with NaOH were investigated [9].
Then, 1 ml of Griess Reagent - B (consisting of 1% sulfanilamide in 5% H3PO4,) was added to the solution.
