AB  - Bu çalışmada, arıtma prosesi maliyetini azaltmak için çevre dostu ve düşük maliyetli kenevir lifleri biyosorbent olarak kullanılarak nikel iyonu giderimi araştırılmıştır. Kenevir liflerinin safsızlıklarını gidermek için sodyum hidroksit ve sitrik asit ile kimyasal modifikasyon yapıldı. Kenevir liflerinin şartlandırılması sonucu elde edilen biyosorbentlerle Ni (II) iyonu adsorpsiyonuna pH ve başlangıç konsantrasyonunun etkileri incelenmiştir. Ayrıca kenevir biyosorbentlerinin (FTIR, XRD, SEM-EDS) karakterizasyon çalışması yapılarak yüzey morfolojisi ve özellikleri incelenmiştir. Elde edilen sonuçlara göre kenevir biyosorbentleri ile Ni (II) iyonu giderimi için optimum pH 4 olarak bulunmuştur. Optimum pH değerinde Ni (II) iyonu giderim verimi %57,34 olarak belirlenmiştir. Başlangıç konsantrasyonu etkisi incelendiğinde, konsantrasyon arttıkça giderim veriminin az da olsa arttığı tespit edilmiştir. Konsantrasyon 40 mg/L iken giderim verimi %61,1 olarak tespit edilmiştir.

N2  - In this study, nickel ion removal was investigated by using environmentally friendly and low-cost hemp fibers as a biosorbent to reduce the treatment process cost. Chemical modification was done with sodium hydroxide and citric acid to remove the impurity of the hemp fibers. The effects of pH, and initial concentration on Ni (II) ion adsorption with biosorbents obtained as a result of conditioning of hemp fibers were investigated. In addition, the characterization study of hemp biosorbents (FTIR, XRD, SEM-EDS) was performed, and the surface morphology and properties were investigated. According to the results, optimum pH was found to be 4 for Ni (II) ion removal with hemp biosorbents. The Ni (II) ion removal efficiency at optimum pH was determined as 57.34%. When the effect of initial concentration was examined, it was determined that the removal efficiency increased slightly as the concentration increased. While the concentration was 40 mg/L, the removal efficiency was determined as 61.1%.
