“…Activated carbon is widely used as a sorbent for water purification from KMnO 4 [14]; for instance, coconut shells, corncob, and bone have been used to synthesize activated carbon and applied for KMnO 4 sorption from aqueous solutions [14,15]. Charcoal and activated carbon were modified by H 2 SO 4 and used for removing of KMnO 4 from wastewater [11,16].…”

The powder of Ocimum Basilicum leaves was treated by zinc chloride (ZnCl2) and applied as a new and low-cost sorbent for extraction of permanganate anions (MnO4−) from liquid phase. The functional groups of the ring stretching vibration, –NH2 deformation, stretching of C-O, stretching of CH, and stretching of –NH were found in the sorbent of zinc chloride Ocimum basilicum leaves powder (ZCOBLP) at 1516.21, 1629.33, 1047.00, 2929.88, and 3294.93 cm−1, respectively. This adsorbent has 8.3 pHZPC, 117.27 m2·g−1 surface area, 0.00711 cc·g−1 pore volume and average pore diameter of 264.144 Å. The outcomes of sorption experiments designate the positive impact for temperature, time of agitation, and started concentration of MnO4− and negative impact for pH. The optimal conditions were 1300 mg·L−1 as started adsorbate concentration, 55°C as solution temperature, agitation time of 420 min, and pH of 1.5. The outcomes of the equilibrium and dynamic approve that this sorption is spontaneous and heat-absorbing process, and the obtained data were described well by isotherm model of Langmuir and 2nd-order dynamic model. The capacities of this sorption were 588.235, 625.000, 666.667, and 714.286 mg·g−1 at 25, 35, 45, and 55 (°C), respectively. The superior sorption capacities of the uncostly ZCOBLP will make it successfully used for MnO4− ions extraction from liquid phases.

“…Once the ripening process has started, the concentration of ethylene gases quickly increases (Saltveit 1999). The amount of corrugated cardboard ethylene absorber was obtained from the calculations of the ethylene production of mango fruit and the optimal ethylene absorption capacity of corrugated cardboard covered with AC-KMnO4, based on our earlier findings (Aprilliani et al 2018). The corrugated cardboard ethylene absorber AC-KMnO4 showed the highest ethylene oxidation capacity of 0.0745 ppm•g -1 , whereas the ethylene oxidation capacity of corrugated cardboard AC was 0.0008 ppm•g -1 .…”

Corrugated cardboard covered with ethylene absorbers is an innovation that can be used to extend the shelf life of mango fruit to slow the loss of fruit quality. Mango fruits ‘Gedong’ were placed in boxes having as the inner parts corrugated cardboard covered with ethylene absorbers. Three storage treatments – corrugated cardboard without ethylene absorber, with activated carbon or activated carbon + potassium permanganate – were used to find the best method to prevent quality deterioration of mango. The color change, mass loss, texture value, and total soluble solids content were evaluated after 10 days of storage. The initial results showed that the highest accumulation of ethylene production by fruit samples was 0.628 ppm·kg−1 on the fourth day after harvest, while the total ethylene production during 8 days of storage was 2.231 ppm·kg−1. The use of ethylene absorbers had significant effects on the quality parameters except for the color changes. Storage for 10 days in boxes lined with corrugated cardboard ethylene absorber in form of activated carbon + potassium permanganate resulted in the lowest mass loss (4.40 ± 2.6%), softness (0.2 ± 0.1 mm·g−1·s−1) and total soluble solids (14.7 ± 1.2 °Brix).

“…For instance, fluidized-bed crystallization method was used [11], concerning the ease of preparation and use, in addition to the high capacity to get rid of permanganate from wastewater adsorption is one of the most extensively utilized processes with different adsorbents [1], activated carbon is a common adsorbent that used for adsorption of KMnO4 from polluted water due to its high adsorption efficiency [12].…”

“…To remove potassium permanganate molecules from polluted aqueous solutions by adsorption a lot of activated carbon adsorbents were prepared using shells of coconut [12], corn cob, and animal bone were also applied [13], sulfuric acid modification of activated carbon, and activated charcoal have been used too [1,14]. More recently, Nanoparticles of metallic oxides have been used to remediate effluent from various dyes [15][16][17][18][19][20][21], Copper sulfide nanoparticles were used as dynamic adsorbents to treat the synthetic wastewater from potassium permanganate ions [22].…”

Seeds powder of Foeniculum vulgare (FVES) was used to prepare a novel adsorbent, the new adsorbent was characterized and its ability to eliminate potassium permanganate (KMnO 4 ) was examined. The impact of KMnO 4 concentration, adsorbent dose, contact temperature, contact time, and solution pH on the adsorption performance was also investigated. The experimental data of this adsorption was analyzed by different kinetic and isotherm models. As Constants of thermodynamic ΔG°, ΔH°, and ΔS° have been also evaluated. Surface area, pore volume, and pore size of the FVESP adsorbent were determined as 0.6806 m 2 .g -1 , 0.00215 cm 3 .g -1 , and 522.063 Å, as pH ZPC of Ox- FVESP was stated to be 7.2. The R 2 values obtained from applying different isotherm and kinetic models (0.999 and 0.996) showed that the adsorption performance of KMnO 4 follows the Langmuir and Pseudo 2 nd order models. Furthermore, high adsorption capacities of 1111.11, 1250.00, and 1428.57 (mg/g) were achieved at three temperatures that were used in this study. Constants of thermodynamic ΔG°, ΔH°, and ΔS° values indicate chemical and spontaneous adsorption at the adsorbent surface.
