Application of Box-Behnken design for modeling of lead adsorption onto unmodified and NaCl-modified zeolite NaA obtained from biosilica
Terzioğlu, Pınar; Yücel, Sevil; Öztürk, Mehmet (Iwa Publishing, 2017)The main objective of the present study was to optimize lead adsorption onto zeolite NaA. For this purpose, to synthesize zeolite NaA under hydrothermal conditions, local wheat husk was precleaned with chemical treatment ... -
The effect of process variables on the properties of nanoporous silica aerogels: an approach to prepare silica aerogels from biosilica
Temel, Tülay Merve; İkizler, Burcu Karakuzu; Terzioğlu, Pınar; Yücel, Sevil; Elalmış, Yeliz Başaran (Springer, 2017)Silica aerogel, a nanoporous material, was produced by using rice husk ash via sol-gel method. The aim of the study is to examine effects of the acid type (acetic, hydrochloric, nitric, oxalic and sulfuric acid), dryer ... -
Review on a novel biosilica source for production of advanced silica-based materials: Wheat husk
Terzioğlu, Pınar; Yücel, Sevil; Kuş, Çiğdem (Wiley, 2019)The growing cognizance of environmental matters elucidates the increasing attention thought the evaluation of bio-based by-products and waste materials in various applications. The agricultural-based industry results in ... -
Synthesis of Zeolite NaA from a New Biosilica Source
Terzioğlu, Pınar; Yücel, Sevil; Öztürk, Mehmet (Springer, 2016)Current study aimed to utilize agricultural waste, wheat husk to produce valuable materials. Amorphous silica (similar to 88 % purity) was extracted from acid leached wheat husk, and used in the synthesis of zeolite NaA. ... -
SYNTHESIS, CHARACTERIZATION, IN VITRO DEGRADABILITY AND BIOACTIVITY OF STRONTIUM SUBSTITUTED RICE HULL ASH SILICA BASED MELT DERIVED 45S5 BIOACTIVE GLASS
Yücel, Sevil; Terzioğlu, Pınar; Sinirlioğlu, Zeynep Aydın; Tekerek, Bilge Sema; Elalmış, Yeliz Başaran (Yildiz Technical Univ, 2015)The purpose of this study was to synthesize strontium substituted melt derived 45S5 bioactive glasses by use of rice hull ash silica and commercial silica. The degradation behaviour of bioactive glass samples was studied ... -
Transesterification of hazelnut oil by ultrasonic irradiation
Kesgin, Cem; Yücel, Sevil; Özçimen, Didem; Terzioğlu, Pınar; Attar, Azade (Taylor & Francis Inc, 2016)Ultrasonic irradiation is considered an effective way to increase mass transfer between immiscible liquid-liquid phases in a heterogeneous system leading to faster transesterification and higher yield and saving excess ...
