In a 23-day study, the independent variables (factors) were initial TLCO concentration, POME FD dosage, and incubation time, and the dependent variable (response) was TLCO biodegradation. The residual TLCO analysis was carried out using the gravimetric method, which was then verified by GCFID. The gravimetric analysis produced a coefficient of determination (R2 = 0.9764) and a probability value (P < 0.0002) indicating significance for the regression model. Similarly, the GCFID analysis identified a coefficient of determination (R2 = 0.9973) and a probability value (P < 0.0001) indicating significance for the regression model. Numerical optimization based on the desirability function was performed, gravimetric and GCFID analyses revealed errors of 4.81 and 1.04, respectively. © 2022 The Authors date: 2022 publisher: Elsevier B.V. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85137044039&doi=10.1016%2fj.seares.2022.102268&partnerID=40&md5=a16f037a678f0e8d60c3146dad60356e id_number: 10.1016/j.seares.2022.102268 full_text_status: none publication: Journal of Sea Research volume: 188 refereed: TRUE issn: 13851101 citation: Sayed, K. and Baloo, L. and Kutty, S.R.B.M. and Al Madhoun, W. and Kankia, M.U. and Jagaba, A.H. and Singa, P.K.
