“…Mainly agricultural waste material as biosorbent is a promising substitution for existing ordinary removal systems due to their high accessibility and fulfils the requirements of environmental sustainability. Biosorption is preferable than other heavy metal expulsion procedure by providing flexible design, High quality treated discharge, regeneration of adsorbent and adsorbate, eco-friendly with high adsorption efficiency [16] . Among the several biopolymers, cellulose has a pronounced advantage in heavy metal removal from wastewater because of the presence of high number of hydroxyl groups presents in cellulose material which obtain great attention and modification of cellulose with non-toxic organic chemicals effectively increases the numbers of chelating sites which aids to remove heavy metal from wastewater [17] .…”

The heavy metals found in contaminated waters are dangerous for the environment and human health, so it is necessary to seek and apply techniques to remove these pollutants, using adsorption techniques with natural biopolymers as cost effective biosorbent. Since large amounts of Jackfruit (Artocarpus heterophyllus fruit) waste part are abandoned after the pulp used around Tepi areas, the possibility of developing value-added products from them is interesting innovation. In this work, cellulose fiber was extracted from Artocarpus heterophyllus fruit waste part and modified with Isopropyl alcohol groups to produce which were then used as Lead metal ion adsorbents. The modified cellulose was characterized by several techniques including Fourier transform infrared spectra (FTIR), scanning electron microscope (SEM), and thermogravimetric analysis (TGA). This modified cellulose was used as adsorbents for adsorption studies of heavy metal ions (Pb2+) within batch adsorption systems. A solution of lead ion (Pb2+) was used as artificial wastewater for the purpose of studying biosorption efficiencies. The biosorption efficiencies of modified cellulose were studied by using four adsorption parameters. The optimum biosorption of modified cellulose at 25 °C, were found to be 94.2%, 76.12%, 82.54%, and 90.13%, of Pb2+ for the adsorption parameter; biosorbent dosage, contact time, Pb (II) concentration, and pH respectively. The biosorption kinetics behaviour of modified cellulose for Pb2+ fitted well with a pseudo-second-order model with correlation coefficient of 0.9975. The biosorption isotherm behaviour was well described using the Langmuir biosorption isotherm model with higher correlation coefficient of 0.9935. The reusability and desorption study of modified cellulose shows that it can be reused 2 to 4 times and after 5th cycles the desorption was significantly decreased. This study showed that the modified cellulosic adsorbents made from (Artocarpus heterophyllus fruit) were able to efficiently adsorb metal ions from aqueous solution.

“…Recently, more and more attention is paid to biological methods of water demanganization [29][30][31]. However, the biochemical oxidation of manganese is a more complex process than sorption and chemical oxidation and is often much slower than these processes [32].…”

Ефективним методом очищення води від сполук марганцю є застосування магнетиту, тому доцільним було вдосконалення методу його використання. В роботі очищення води від іонів марганцю проводили в динамічних умовах при фільтруванні води через шар сильнокислотного катіоніту КУ-2-8 в H+, Na+, Ca2+ формах модифікованого магнетитом. Це дозволяє забезпечити постійний контакт розчину з іонообмінним матеріалом та знижує роль лімітуючого дифузійного фактору на процес очищення води. При оцінці ефективності катіоніту КУ-2-8 при вилученні іонів Mn2+ із води в залежності від форми іоніту було встановлено, що ПОДЄ для іоніту в H+, формі становить 2198 мг-екв/дм3, Na+ – 2175 мг-екв/дм3, Ca2+ – 1717 мг-екв/дм3. Отже, при переході від H+ до Na+ і до Ca2+ форми відбувається зниження сорбційної здатності катіоніту КУ-2-8 по іонах Mn2+. При підвищенні початкової концентрації з 5 до 10 та 30 мг/дм3 в дистильованій воді залишкова концентрація зростає від 0.14 до 0.35 та до 1.95 мг/дм3 при фільтрування через 10 см3 іоніту в Ca2+ формі. При вилученні іонів Mn2+ із артезіанської води залишкові концентрація становили 4.0; 7.0 та 27.0 мг/дм3 відповідно. Отже, на модифікованому магнетитом катіоніті іони марганцю вилучаються лише частково за рахунок іонного обміну, а повне вилучення їх із води можливе лише за рахунок каталітичного окислення та висадження на магнетиті.
