| Abstract | ||
| BIAMP was used to determine Sn2+, optimum conditions were maximum absorption of complex at (523 nm), pH (9), temperature (40 ºc) . Beer's law was obeyed in the range (0.02-1.8) ppm, detection limit was (0.0009) ppm, linearity ( R2 ) was (0.9995), correlation factor (r) was (0.9997), molar absorbitivty (ε) was 4.09 x 104 L.mol-1.cm-1 . The ratio between metal to ligand was (1:2) of complex, Statistical units were recorded, R.S.D % (1.63) % and Erel.% and Re % were (-1.66) %, (98.34) % . The interferences of ions were study. | ||
