human health. For this reason, these substances must be removed from drinking water via a proper method. Metal Organic Frameworks (MOFs) are novel adsorbents that have been widely considered in recent years.

Additionally, isotherms and kinetics of humic acid adsorption on Uio-66-NH2 adsorbent were determined. The data analysis and isotherms comparisons were conducted using linear regression and determination coefficient.</span></span><span dir="RTL" lang="AR-SA" style="font-size:9.5pt"><span style="font-family:Nazanin"></span></span></span></span></span><br> <span style="font-size:8.5pt"><span style="line-height:17pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:13.0pt">Results: </span></i></b><span lang="EN" style="font-size:12.0pt"><span style="color:#222222">In this study, the analysis confirmed the structure and properties of the fabricated nanoparticles. The adsorbent surface area was 673.4 m²/g. The results also showed that the optimal pH for adsorption of humic acid was in the range of 5 to 7, the optimal dose of adsorbent was 0.8 g/L, and the maximum adsorption of humic acid was 2.2 mg/g of adsorbent.</span></span><b><i><span style="font-size:13.0pt"></span></i></b></span></span></span><br> <span style="font-size:8.5pt"><span style="line-height:17pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:13.0pt">Conclusion: </span></i></b><span lang="EN" style="font-size:12.0pt"><span style="color:#222222">Based on the findings of the present research, humic acid adsorption isotherm on the adsorbent was in accordance with the Langmuir isotherm model and its adsorption kinetics followed the pseudo-second-order kinetic model. The current study revealed that by optimization of the condition, the adsorbent can be used for organic matter removal.</span></span></span></span></span><br> &nbsp;</div> چارچوب فلزی آلی, جذب سطحی, اسید هیومیک, ایزوترم جذب, سینتیک جذب Adsorption kinetics, Adsorption isotherm, Humic acid, Metal organic framework, Surface adsorption 1 14 http://yafte.lums.ac.ir/browse.php?a_code=A-10-1643-3&slc_lang=fa&sid=1 Mansour Ghaderpouri منصور قادرپوری mghaderpoori 7200319475328460027003 7200319475328460027003 No Department of Environmental Health, Faculty of Health and Nutrition, Lorestan University of Medical Sciences, Khorramabad, Iran مرکز تحقیقات بهداشت محیط، گروه مهندسی بهداشت محیط، دانشکده بهداشت و تغذیه، دانشگاه علوم پزشکی لرستان، ایران Ali Jafari علی جعفری jafari_a99@yahoo.com 7200319475328460027004 7200319475328460027004 Yes Department of Environmental Health, School of Health, Kermanshah University of Medical Sciences, Kermanshah گروه مهندسی بهداشت محیط، دانشکده بهداشت، دانشگاه علوم پزشکی کرمانشاه، ایران Mahdieh Janbozorgi مهدیه جانبزرگی mah_jan1372 7200319475328460027005 7200319475328460027005 No Department of Environmental Health, Faculty of Health and Nutrition, Lorestan University of Medical Sciences, Khorramabad, Iran مهندسی بهداشت محیط، دانشکده بهداشت و تغذیه، دانشگاه علوم پزشکی لرستان، ایران
