Acoustic analysis of a liquefied petroleum gas-fired pulse combustor

Kılıçarslan, Ali; Arısoy, Arif (2008)

Experimental investigation of acoustic characteristics of a Helmholtz type liquefied petroleum gas-fired pulse combustor is presented. In the experiments, the length of the tail pipe was changed from 1.9 m to 1.3 m by 10 ...

Adsorption of Brilliant Green from Aqueous Solutions onto Crosslinked Chitosan Graft Copolymers

Özkahraman, Bengi; Bal, Ayça; Acar, Işıl; Güçlü, Gamze (2011)

In this study, graft copolymerization of itaconic acid (IA) and crotonic acid (CA) onto the crosslinked chitosan beads were carried out using ammonium persulfate as initiator. Grafted chitosan beads were characterized by ...

Adsorption of Congo red from aqueous solution onto KOH-activated biochar produced via pyrolysis of pine cone and modeling of the process using artificial neural network

Kaya, Nihan; Yıldız Uzun, Zeynep; Altuncan, Ceren; Uzun, Harun (Springer Heidelberg, 2021)

Most of dyes cause various environmental and health problems due to their toxic, mutagenic, and even carcinogenic properties. Therefore, several treatment methods are used to remove dyes from wastewater. Adsorption is one ...

ADSORPTION OF DIAZO DYE DIRECT RED-28 AND TETRA-AZO DYE DIRECT BLACK-22 USING CALCINED KAOLIN IN AQUEOUS SOLUTIONS

Fındık, Serap (CHEM SOC ETHIOPIA, 2023)

ABSTRACT. In this study, the removal of diazo and tetra-azo dyes using calcined kaolin were compared. Direct red-28 (DR-28) and Direct black-22 (DB-22) was chosen as diazo and tetra-azo dyes, respectively. The kaolin ...
