The\nprepared samples were used as sorbent for the removal of dyes (malachite green)\nfrom aqueous solution. According to the bulk density, surface area and preliminary\nsorption properties of prepared samples, neem bark powder (NBP), acid activated\nneem bark powder (AANBP-2) and heat treated neem bark powder (HTNBP-4) were\nchosen for further study for removal of dye. The physicochemical properties\n(moisture content, ash content, pH, bulk density and specific surface area) of\nprepared samples were determined by conventional methods. The prepared sorbent\nsamples (NBP, AANBP-2 and HTNBP-4) were characterized by modern techniques\nsuch as SEM and FT IR. The sorption capacities of prepared NBP, AANBP-2,\nHTNBP-4 were studied for the removal of dye (malachite green) from aqueous\nsolution with varying parameters of pH, initial concentration of dye solution, contact\ntime and dosage of adsorbent. The removal percent of malachite green was found to\nbe 92.881 %, 93.880 %, 95.828 % for NBP, AANBP-2 and HTNBP-4 at optimum\nconditions (pH 4, initial concentration 400 ppm, contact time 120 min and dosage of\nadsorbent 0.2 g). Langmuir and Freundlich isotherms were employed to describe\nadsorption capacities. In the sorption isotherm studies, Langmuir isotherm indicated\nthat the sorption capacities (Q0) of NBP, AANBP-2, HTNBP-4 were 370.370 mg g-1,\n384.615 mg g-1 and 400.000 mg g-1 for the removal of malachite green respectively.\nFrom the Freundlich isotherm studies, the sorption capacity (Kf) of HTNBP-4 is\nlarger than NBP and AANBP-2 for the removal of malachite green. The application\nof sorbents were investigated for the removal of textile dyes from textile mill effuents\ncollected from drainage of textile mill in North Dagon Township, Yangon Region.\nThe removal percent of textile dye by NBP, AANBP-2 and HTNBP-4 were observed\nas 55.662 %, 65.470 % and 81.100 %. HTNBP-4 was the more effective and\nefficient sorbent for malachite green dye and textile effluent. NBP, AANBP-2 and\nHTNBP-4 could be applied in purifying the environmentally polluted wastewater\neffluents."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Neem bark powder"}, {"interim": "Malachite green"}, {"interim": "Wastewater"}, {"interim": "Textile dyes"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-12-24"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Htay Htay Nyunt, Thinzar Nu.pdf", "filesize": [{"value": "414 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 414000.0, "url": {"url": "https://meral.edu.mm/record/7030/files/Htay Htay Nyunt, Thinzar Nu.pdf"}, "version_id": "145038ab-ebb5-4004-a280-2b9198cae727"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Maubin University Research Journal", "subitem_pages": "p. 149-161", "subitem_volume": "Vol.11"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Htay Htay Nyunt"}, {"subitem_authors_fullname": "Thinzar Nu"}, {"subitem_authors_fullname": "Khin Than Yee"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2020-12-01"}, "item_title": "Removal of Malachite Green Using Activated Azadirachta indica A.
