“…Among these contaminants, synthetic dyes are the main source of water pollutants in the textile industry. The reactive dye on release in the water disturbs its physico-chemical properties and deteriorates the quality of the aquatic system (Khamparia and Jaspal 2016). Due to their complex molecular structure, these dyes are resistant to the conventional biological treatment of wastewater (Sonwani et al 2019).…”

In this study, four biochars prepared from different crop residue waste i.e. sugarcane bagasse (SBB), coconut shell (CNB), paddy straw (PDB), and distilled waste of lemongrass (LGB) were evaluated for removal of Remazol Brilliant Blue R from the aqueous system. The RBBR adsorption capacities of biochar were 97–79% for SBB, 99.9–99.47% for CNB, 66.1–48% for PDB, and 78–68% for LGB, dominantly controlled by their aromaticity and mineral content. The Langmuir and Freundlich isotherms and pseudo-second-order kinetic models have described the chemisorption of RBBR on biochar surfaces. The thermodynamic data suggested that adsorption was spontaneous and endothermic. These biochars demonstrated excellent reusability (till four cycles with 50–61% regeneration). The purified water and biochar dye sludge demonstrated no phytotoxicity. The findings obtained in this study may provide supports for the potential of biochars for anionic dye removal from water and utilization of generated sludge for zero waste-producing technologies in the future.

“…The authors concluded that the adsorption capacity rose from approximately 6 to 11.17 mg/g when diminishing the particle size more than a half from 150 μm. Similarly, Khamparia and Jaspal (2016) found that the removal efficiency of Rhodamine B by Argemone mexicana seed-based adsorbent inclined significantly in tune with the decrease in the particles size from 710 to 300 μm. Regardless of the fact that size reduction demands a noticeable amount of resources and cost…”

Invasive plants as biosorbents for environmental remediation: a review

et al. 2022

Water contamination is an environmental burden for the next generations, calling for advanced methods such as adsorption to remove pollutants. For instance, unwanted biowaste and invasive plants can be converted into biosorbents for environmental remediation. This would partly solve the negative effects of invasive plants, estimated at 120 billion dollars in the USA.Here we review the distribution, impact, and use of invasive plants for water treatment, with emphasis on the preparation of biosorbents and removal of pollutants such as cadmium, lead, copper, zinc, nickel, mercury, chromate, synthetic dyes, and fossil fuels. Those biosorbents can remove 90-99% heavy metals from aqueous solutions. High adsorption capacities of 476.190 mg/g for synthetic dyes and 211 g/g for diesel oils have been observed. We also discuss the regeneration of these biosorbents.

“…Bir adsorbat-adsorban sistemi için adsorpsiyon kapasitesi ile adsorpsiyonun doğası arasındaki ilişki, gerek adsorpsiyon mekanizmasının açıklanması gerekse adsorpsiyon prosesinin optimize edilmesine yardımcı olması nedeniyle oldukça önemlidir. Bu bağlamda adsorpsiyon izotermleri, adsorpsiyon mekanizmasının belirlenmesini sağlayan önemli bir unsurdur [1,36]. Genellikle adsorpsiyon izotermleri, çözünen-çözücü etkileşimini, adsorbanın adsorplama kabiliyetini ve adsorban yüzeyinde adsorbat birikme derecesini araştırmak için kullanılır.…”

Bu çalışmada çam kozalağının pirolizi ile elde edilen aktif karbon, sulu çözeltilerden Rodamin B boyasının gideriminde adsorban olarak kullanılmıştır. Üretilen aktif karbon 4 farklı kimyasal katalizör (ZnCl2, H3PO4, H2SO4 ve KOH) ile modifiye edilerek, aktivasyon işleminin adsorpsiyon verimliliği üzerine etkisi incelenmiştir. Adsorpsiyon deneyleri kesikli sistemde çalışılmış ve baslangıç boya konsantrasyonu, temas süresi, pH ve sıcaklık gibi parametrelerin adsorpsiyon prosesi üzerine etkisi araştırılmıştır. Maksimum boya giderimi pH=3,0’de gözlemlenmiştir. Başlangıçtaki boya konsantrasyonunun artmasıyla Rodamin B adsorpsiyonu azalmıştır. Temas süresinin artmasıyla Rodamin B'nin giderim verimi artmıştır ve yaklaşık 30 dakika içinde dengeye ulaşılmıştır. Aktif karbonun KOH ile aktivasyonu sonucu en yüksek boya uzaklaştırma verimi (%49,71) elde edilmiştir. Deneysel sonuçlar, Langmuir ve Freundlich izoterm modellerine uygunlukları açısından incelenmiştir. Korelasyon katsayılarına göre Langmuir izoterm modelinin bu çalışmada elde edilen deneysel verilere daha uygun olduğu bulunmuştur. Hesaplanan termodinamik parametrelerle birlikte adsorpsiyon mekanizması açıklanmaya çalışılmıştır. Buna göre elde edilen pozitif ∆G değerleri adsorpsiyon prosesinin kendiliğinden olmadığını, pozitif ∆H ve ∆S değerleri ise adsorpsiyon prosesinin endotermik ve rastgele olduğunu göstermiştir.
