“…After equilibrium is achieved, any increase in the treatment time on the adsorption efficiency is not beneficial, and the adsorption capacity is fixed while other variables remain constant at the optimum values. These results have been indicated by [40] in their conclusions.…”

“…Tea is consumed worldwide in large quantities daily. As a result of this consumption, very large quantities of tea leaves are accumulated, which must be disposed of in economical, safe and environmentally friendly ways [40]. This paper studies the adsorption possibility of copper ions (Cu +2 ) from polluted water by using tea leaves as an available, cheap and non-toxic adsorbent media in a laboratory batch-mode unit.…”

The possibility of recovering one of the famous heavy metal ions, divalent copper, from contaminated aqueous solutions (which simulates wastewater) was studied in this study. The removal method was adsorption technique using a laboratory batch-mode unit, while the used tea leaves were the adsorption media. The adsorption process was performed under various operating conditions and ranges that simulate the natural environmental conditions to determine the ideal values that achieve the maximum removal of copper ions. The acquired results demonstrated that the maximum remediation efficiency was 85%, which was achieved at treatment time, shaking speed, initial concentration, temperature, acid function, and adsorption dose of 90 min, 250 rpm, 70 ppm, 25°C, 4, 4.5 g, respectively. The values of the thermodynamic properties demonstrated that adsorption is spontaneous, exothermic and has negative entropy, while adsorption follows Langmuir’s model and the second pseudo-model according to the isotherm and kinetic studies, respectively. To conduct the Zero Residues Level concept, the loaded used tea leaves were prepared to study it effect as a simple type of rodenticide by applying it to Sprague Dawley rats. The results of the test show that the effectiveness of utilizing the residues as rodenticide and the LD50 of the proposed rodenticide were identical to those mentioned in the literature. Based on these results, the current study sheds light on the possibility of converting used tea leaves from harmful solid waste to an environmentally friendly substance using it as an effective adsorbent medium for the treatment of water polluted with heavy metals.

“…Among various treatment methods, the adsorption method due to its cost effective, simplicity, high effectiveness and availability of a large range of adsorbents have been applied [29][30][31] . One of the eco-friendly elimination of contaminants of e uents are carbonaceous sources in producing adsorbents from agricultural and food waste including wood sawdust 32 , coconut shells 33 , orange peel 34 , oak shell 35 , palm-kernel shells 36 , wood chips 37 , rice husk 38 , corn cobs 39 , seeds 40 , etc. In order to activate these carbonaceous sources physical and chemical activation should be done on these agricultural residues.…”

This work presents a significant highly porous activated magnetic carbon nanoparticles (MPFRC-A) derived from pine fruit residue through physical activation (carbonization temperature: 110–550◦C), chemical activation (H2SO4 (0.1 N, 96%)), and Co-precipitation processes and then using it for removing tetracycline (TC) and paracetamol (PC) from water and evaluating via the spectrophotometer (DR6000). Functionalization of Fe3O4 nanoparticles on the surface of (PFR-AS) generated high saturation magnetization that causes to separate from aqueous solution by an external magnet. MPFR-AS adsorbent was evaluated by Brunauer-Emmet-Teller (BET) analyzer, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-Ray diffraction analysis (XRD) and Raman spectroscopy (RM). In the experimental sector, the effect of different items including, pH, contact time, initial concentrations, adsorbent dosage, and temperature on the adsorption processes were investigated and based on them the adsorption isotherm modules, and kinetics were studied and concluded. Results indicated that MPFR-A exhibited a large specific surface area (182.5 m2/g) and high total pore volume (0.33 cm3/g). The maximum adsorption capacity was obtained at pH = 4,5, adsorbent dose: 400 mg and initial concentration of 20 mg/L at 25°C. The study showed that experimental data were well-fitted by Langmuir isotherm model (R2 > 0.98) and the maximum uptake capacities for TC was 43.75 mg/g and for PC was 41.7 mg/g.

Bu çalışmada, analizi yapılacak numunelerin sıvı-sıvı mikroekstraksiyon ile önderiştirilmelerinin ardından özgün tasarımlı dijital görüntüleme kutusu kullanılarak antimonun(III) kolorimetrik tayinine yönelik yöntem geliştirilmiştir. Önderiştirme aşamasında numune içerisindeki antimon ile kompleks oluşturması amacıyla ditizon ligand olarak kullanılmıştır. Önderiştime işleminden sonra elde edilen renkli örnekler dijital görüntüleme kutusu içerisine yerleştirilmiş ve akıllı telefonlara yüklenebilen bir uygulama kullanılarak kolorimetrik analiz gerçekleştirilmiştir. Analizlere başlanmadan önce dijital görüntüleme kutusu içerisine yerleştirilen kuvars küvetin merceğe olan uzaklığı, kuvars küvet üzerinde kolorimetrik tayinin yapılacağı noktanın konumu ve analiz edilecek noktanın yarıçapına yönelik optimizasyon çalışması yapılmıştır. Optimum koşullar altında farklı derişimlere sahip antimon numelerinin analizi sonucunda 1-4 mg/L aralığında lineer bölge elde edilmiş ve antimon için tayin limiti (LOD) 0,71 mg/L olarak hesaplanmıştır. Çalışmada en düşük konsantrasyon için yüzde bağıl standart sapma %0,33 (n=8) olarak bulunmuştur. Bu değer, yapılan analizin yüksek hassasiyete sahip olduğunu göstermektedir.
