The production of propylene from propane dehydrogenation process in the petrochemical sector regularly produce high concentration of sulphur in the form of sodium sulphide (Na2S). High concentration of sulphide can lead to corrosion in sewage pipes, massive fish kill and obnoxious odors into the atmosphere. Adsorption technique using lowcost and environmentally friendly adsorbents derived from natural resources such as rice husk ash (RHA) may offer a suitable alternative for in situ removal of contaminants such as sodium sulphide in industrial wastewater. In this work, the use of silica synthesized from RHA was investigated for its potential in removing high concentration of sulphide (S 2-) in the form of sodium sulphide from wastewater. Results showed that pure silica with the size around 0.9 to 2.0 μm was successfully synthesized from RHA. Significant reduction of sulphide level was observed after being treated with RHAbased silica calcined with clay compared to other adsorbents such as chemically treated nanoporous zeolite and natural clay itself with more than 90 % removal after 120 minutes of treatment with the value of the pseudo-first-order rate constant, k of 0.1404, 0.14 and 0.1519 for silica compared to zeolite. This suggests that the use of silica derived from RHA has a potential to be used as sulphide remover in industrial wastewater without extensive chemical treatment to improve its removal capacity.

“…Диоксид кремния является основным минеральным компонентом РШ, которая также содержит примеси металлов, процентное содержание каждого при этом составляет меньше 1% [9][10]. При сжигании РШ может быть получено около 20% золы [11,12], которая в свою очередь содержит около 87-98% диоксида кремния [13,14].…”

Белорусский государственный технологический университет 2 Казахский национальный университет имени аль-Фараби УГЛЕРОД-КРЕМНИСТЫЙ НАПОЛНИТЕЛЬ ДЛЯ ЭЛАСТОМЕРНЫХ КОМПОЗИЦИЙРазработка полимерных композиционных материалов с использованием различных экологически чистых наполнителей является областью активных исследований. Основная цель данной работы заключается в изучении структуры и химического состава углерод-кремнистого композита (УКК), полученного путем карбонизации смеси рисовой шелухи и рисового стебля в пиролизной печи без доступа кислорода, при температуре 550-600°С, до и после механоактивации. Химический состав УКК определен методом рентгенофазового анализа. Установлено, что композит состоит из углерода (35,0-60,0 ± 2,0%), диоксида кремния (30,0-50,0 ± 2,0%) и примесей оксидов металлов различной природы, а также содержит аморфную фракцию оксида кремния. Изучены основные физико-химические характеристики углерод-кремнистого композита. Методом сканирующей электронной микроскопии исследована структура композита. Выявленно, что она представляет собой в основном агрегаты со средним размером частиц 50,9 мкм, состоящие из слоистых образований с развитой внутренней системой пор. Определена площадь поверхности композита методом многоточечной адсорбции газов азота по методу БЭТ, которая составляет 36 м 2 /г. Осуществлена механоактивация УКК путем измельчения в вибрационной и планетарной мельницах при различном времени. Зафиксировано, что продолжительность механоактивации углеродкремнистого композита способствует увеличению удельной поверхности композита.

“…The stretching of aromatic rings from lignin appeared at 1508.32 cm -1 and 1458.17 cm -1 for RH adsorbent. Bands at 1080.13 cm -1 also defined the presence of O-Si-O vibration attributable to asymmetrical stretching band vibration (Ferraro et al, 2010 ;Hadipramana et al, 2016). The vibration of C-O-H bending (ester) at 1450-1375 cm -1 , C-H bending 900-690 cm -1 and C-C stretch at 700-400 cm -1 (Syafri et al, 2011) were present.…”

ÖZET: Bu çalışmada; pirinç kabuğu ve yanmış pirinç kabuğu (yakılarak aktif karbon formuna getirilmiş) katyonik bir boyar madde olan Bazik Yellow 51(BY51) boyar maddesinin sulu çözeltiden adsorpsiyonla gideriminde düşük maliyetli bir adsorbent olarak kullanılmıştır. Pirinç kabuğu ve yanmış pirinç kabuğunun karakterizasyonu SEM (Scanning Electron Microscope) ve FTIR (Fourier Transform Infrared Spectroscopy) kullanılarak yapılmıştır. Başlangıç boyar madde konsantrasyonu ve temas süresi, pH, sıcaklık dahil olmak üzere tüm operasyonel parametrelerin boyar madde giderim verimi üzerine etkileri incelenmiştir. Tüm çalışmalar kesikli modda yapılmıştır. Adsorpsiyon verileri Langmuir ve Freundlich izoterm modellerine uyarlanarak analizi yapılmış ve tek tabaka adsorpsiyon kapasitesi hesaplanmıştır. Kinetik veriler yalancı birinci ve yalancı ikinci mertebe kinetik modellerine uyarlanmış ve yalancı ikinci mertebe kinetik modeline uyduğu tespit edilmiştir. Entalpi (H°), entropi (S°) ve serbest enerji değişimleri (G°) gibi termodinamik parametreler de incelenmiştir. Serbest enerji değişimi Bazik Yellow 51 boyar madde adsorpsiyonunun pirinç kabuğu ve yanmış pirinç kabuğu için çalışılan tüm sıcaklıklarda kendiğilinden gerçekleşebileceğini göstermiştir. Bu durum da pirinç kabuğu ve vanmış pirinç kabuğunun, sulu çözeltiden katyonik boyar madde giderimi için uygun bir adsorbent olarak kullanılabileceğini göstermiştir.
