Patent number: 11192804Abstract: A method of using a nanoporous carbon material for adsorption of one or more PAH and diesel fuel from an aqueous solution is described. The aqueous solution may comprise the one or more PAH at a concentration of 0.1 mg/L-1 g/L, and the diesel fuel at a concentration of 0.1-5 g/L. The nanoporous carbon material may adsorb at least 96 wt % of one or more PAH within 10 minutes. The nanoporous carbon material may be obtained by contacting a carbonized asphalt with a base.Type: GrantFiled: November 19, 2019Date of Patent: December 7, 2021Assignee: King Fahd University of Petroleum and MineralsInventors: Mohammad Nahid Siddiqui, Basheer Chanbasha, Faisal Mohammed Al-Issa

Patent number: 9664645Abstract: A method of detecting and quantifying perchlorate contamination in samples, especially samples with complex background matrices such as food and produce with trace levels of perchlorate. A simple microwave assisted-electromembrane extraction provides simultaneous reduced extraction time, sample clean-up, high recovery and enrichment of perchlorate ions for detection and quantification by ion chromatography. Three parallel EME experiments connected to a single DC power supply improves the precision of the analyses. It also couples well with the multiple microwave digested samples and this reduces the sample preparation time and is hence suitable for routine environmental applications.Type: GrantFiled: November 20, 2014Date of Patent: May 30, 2017Assignee: King Fahd University of Petroleum and MineralsInventors: Basheer Chanbasha, Hakimu Nsubuga

Patent number: 9568460Abstract: A liquid phase microextraction (LPME) method was developed for the determination of sulfur compounds in crude oils and its fractions (e.g diesel). Wide ranges of sulfur compounds including benzothiophene, dibenzothiophene and their derivatives were used as model compounds for extraction. After extraction, the analyses were performed by gas chromatography equipped with sulfur chemiluminescence detector (GC-SCD). Various experiments conditions influencing the extraction such as extraction times, extraction solvents, solvent volume and quantitative parameters were optimized to achieve higher extraction efficiency and high accuracy. The optimized conditions were applied to the determination of sulfur compounds in crude oil and diesel.Type: GrantFiled: August 28, 2014Date of Patent: February 14, 2017Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Basheer Chanbasha, Ibrahim Mohammed Al-Zahrani, Than Htun

Publication number: 20150377845Abstract: A fully automated flow assisted-solid-phase microextraction (FA-SPME) is developed for the determination of chloroethers in aqueous samples. A CTC CombiPAL autosampler coupled with gas chromatography-mass spectrometry (GC-MS) is used to automate the extraction process. In this method, the SPME fiber is exposed to a sample in direct immersion. After exposure, the fiber is desorbed at the injection port of GC-MS.Type: ApplicationFiled: September 4, 2015Publication date: December 31, 2015Applicants: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS, King Abdulaziz City for Science and TechnologyInventors: Basheer CHANBASHA, Mousa Yaser AMAYREH
