3-chloroaniline (3CA) concentrations were measured in aqueous solution by UV/Vis spectrophotometer. Validation of the calibration curve’s linearity, instrumental precision (RSD%), limits detection and quantification accomplished. The coefficient curve (1.0–10.0 mgL?1 3CA) had a high correlation (R2 = 0.9997) was range (RSD% 0.50–0.74%, n 10). LOD LOQ from regression analysis 0.20 0.61 mgL?1, re...
توسعه تکنولوژی و مصارف صنعتی از فلزات و نمکهای آنان موجب تشدید روز افزون آلودگی محیط زیست از طریق فلزات سنگین میباشد که لازم میباشد با اعمال روشهای مناسب این فلزات را قبل از ورود پسابها به محیط زیست آنها جدا نمود. از جمله روشهای معمول برای جداسازی این فلزات روش اسمز معکوس و تبخیر، ته نشینی، شفاف سازی تکنیک کربن فعال و رزینهای تبادل یونی میباشد. در سالهای اخیر نیز روش جذب بیولوژیکی به عنوان یکی ...
