Experimentally; the Δlog K coefficients were calculated; the positive values indicated that the ternary complexes is more stable than the binary complexes. However, addition of AA and Back tea to Fe (II) reported that disappear of d-d transition which indicate that the Fe-polyphenols complexes were not formed. Theoretically, molecular geometry and electronic structure of the molecules were calculated and discussed using DFT.</p> <div class="alert alert-info text-left"><b>నిరాకరణ:</b> ఈ సారాంశం కృత్రిమ మేధస్సు సాధనాలను ఉపయోగించి అనువదించబడింది మరియు ఇంకా సమీక్షించబడలేదు లేదా ధృవీకరించబడలేదు.</div> <div class="nav social-icons"> <a class="nav-link w-auto">ఈ కథనాన్ని భాగస్వామ్యం చేయండి</a> <a title="ఇక్కడ నొక్కండి" target="_blank" href="https://www.facebook.com/sharer.php?u=https://telugu.longdom.org/abstract/spectrophotometric-potentiometric-and-conductometric-study-for-binary-andrnternary-complexes-of-fe-ii-as-modeling-of-fep-93740.html" rel="noopener"><i class="fab fa-facebook-f"></i></a> <a class="nav-link" title="ఇక్కడ నొక్కండి" target="_blank" href="https://twitter.com/share?url=https://telugu.longdom.org/abstract/spectrophotometric-potentiometric-and-conductometric-study-for-binary-andrnternary-complexes-of-fe-ii-as-modeling-of-fep-93740.html" rel="noopener"><i class="fab fa-twitter"></i></a> <a class="nav-link" title="ఇక్కడ నొక్కండి" target="_blank" href="https://www.linkedin.com/shareArticle?mini=true&url=https://telugu.longdom.org/abstract/spectrophotometric-potentiometric-and-conductometric-study-for-binary-andrnternary-complexes-of-fe-ii-as-modeling-of-fep-93740.html" rel="noopener"><i class="fab fa-linkedin-in"></i></a> <a class="nav-link" title="ఇక్కడ నొక్కండి" target="_blank" href="https://plus.google.com/share?url=https://telugu.longdom.org/abstract/spectrophotometric-potentiometric-and-conductometric-study-for-binary-andrnternary-complexes-of-fe-ii-as-modeling-of-fep-93740.html" rel="noopener"><i class="fab fa-google-plus-g"></i></a> </div> </div> </div> </div> </section> <footer class="bg-blue-grey-900 py-3"> <div class="container"> <div class="row"> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">కంటెంట్ లింక్‌లు</h4> <ul class="list-unstyled footer-links font-size-3"> <li><a class="" href="https://telugu.longdom.org/privacy-policy.html" title="ఇక్కడ నొక్కండి">గోప్యతా విధానం</a></li> <li><a class="" href="https://telugu.longdom.org/terms-conditions.html" title="ఇక్కడ నొక్కండి">నిబంధనలు & షరతులు</a></li> <li><a class="" href="https://telugu.longdom.org/authors-reviewers-editors.html" title="ఇక్కడ నొక్కండి">రచయితలు, సమీక్షకులు & ఎడిటో</a></li> </ul> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">లాంగ్‌డమ్‌ను సంప్రదించండి</h4> <p><strong>లాంగ్‌డమ్ గ్రూప్ SA</strong><br /> అవెన్యూ రోజర్ వాండెండ్రీస్చే,<br /> 18, 1150 బ్రస్సెల్స్, బెల్జియం<br /> ఫోన్: +442038085340<br /> <strong>ఇమెయిల్:</strong> <a class="white" href="mailto:info@longdom.org" title="Click here">info@longdom.org</a></p> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">కనెక్ట్ చేయండి</h4> <nav class="nav nav-pills social-icons-footer flex-column a-pl-0"> <a href="https://www.facebook.com/longdompublisher" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-facebook-hover"><i class="fab fa-facebook-f bg-facebook"></i></a> <a href="https://www.linkedin.com/company/longdom-publishing-sl/" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-linkedin-hover"><i class="fab fa-linkedin-in bg-linkedin"></i></a> <a href="https://twitter.com/LongdomP" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-twitter-hover"><i class="fab fa-twitter bg-twitter"></i></a> <a href="https://www.instagram.com/longdom_publisher/" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-instagram-hover"><i class="fab fa-instagram bg-instagram"></i></a> </nav> </div> </div> <div class="row text-center"> <div class="col"> <p>కాపీరైట్ © 2024 <a href="https://telugu.longdom.org/" title="ఇక్కడ నొక్కండి" class="white">లాంగ్‌డమ్ పబ్లిషింగ్ SL</a>.</p> </div> </div> </div> </footer>  <a href="#0" class="cd-top js-cd-top">Top</a>   <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>  <script> jQuery(function($) { $(window).scroll(function fix_element() { $('#target').css( $(window).scrollTop() > 100 ?
