The present study was conducted to determine the potential of utilizing the FeSO4·7H2O waste from the titanium manufacturing industry as an effective coagulant for treating industrial effluent. In this study, the secondary rubber processing effluent (SRPE) was treated using ferrous sulfate (FeSO4·7H2O) waste from the titanium oxide manufacturing industry. The FeSO4·7H2O waste coagulation efficiency was evaluated on the elimination of ammoniacal nitrogen (NH3-N) and chemical oxygen demand (COD) from SRPE. The central composite design (CCD) of experiments was employed to design the coagulation experiments with varying coagulation time, coagulant doses, and temperature. The coagulation experiments were optimized on the optimal elimination of NH3-N and COD using response surface methodology (RSM). Results showed that coagulant doses and temperature significantly influenced NH3-N and COD elimination from SRPE. The highest NH3-N and COD removal obtained were 98.19% and 93.86%, respectively, at the optimized coagulation experimental conditions of coagulation time 70 min, coagulant doses 900 mg/L, and temperature 62 °C. The residual NH3-N and COD in treated SPRE were found below the specified industrial effluent discharge limits set by DoE, Malaysia. Additionally, the sludge generated after coagulation of SRPE contains essential plant nutrients. The present study’s finding showed that FeSO4·7H2O waste generated as an industrial byproduct in a titanium oxide manufacturing industry could be utilized as an eco-friendly coagulant in treating industrial effluent.

“…Furthermore, roots of the opt3 mutant were also copper deficient (Figure 2B). Past findings from different research groups, showing the overaccumulation of iron under copper deficiency in roots and leaves of A. thaliana, are especially relevant (Figure 11A based on Waters and Armbrust, 2013;Kastoori Ramamurthy et al, 2018;Kroh and Pilon, 2020;Rai et al, 2021;.…”

Copper and iron are micronutrients but are toxic when they accumulate in cells in excess. Crosstalk between copper and iron homeostasis in Arabidopsis thaliana has been documented and includes iron accumulation under copper deficiency and vice versa. However, molecular components of this crosstalk are not well understood. Iron concentration in the phloem has been suggested to act systemically, negatively regulating iron uptake to the root. Consistently, systemic iron signaling is disrupted in A. thaliana mutants lacking the phloem companion cell-localized iron transporter, AtOPT3, and opt3 mutants hyperaccumulate iron. Here, we report that in addition to iron, AtOPT3 transports copper and mediates copper loading to the phloem for delivery from sources to sinks. As a result of this function, the opt3-3 mutant accumulates less copper in the phloem, roots, developing leaves and embryos compared to wild type, is sensitive to copper deficiency, and mounts transcriptional copper deficiency response. Because copper deficiency has been shown to stimulate iron accumulation, we propose that reduced copper concentration in the phloem of the opt3-3 mutant and its constitutive copper deficiency contribute to iron overaccumulation in its tissues. Our data assign new transport capabilities to AtOPT3 and increase understanding of copper - iron interactions and signaling.

“…Both Fe and Mn are essential micronutrients for plants, but they have been shown to elicit different, and sometimes opposite, responses when they are scarce in the growth medium [ 32 , 35 , 36 ]. In the results shown here, this antagonism is reflected in contrasting changes in oxidoreductase enzymes, coumarin production, and protein and energy metabolism.…”

“…There is a certain level of antagonism between Fe and Mn homeostasis in plants [ 35 ], with demonstrated interference in the uptake of one metal by the other [ 36 ]. Metal transporters often have broad specificity, working with many divalent cations, and therefore Fe and Mn share several of them.…”

Iron (Fe) and manganese (Mn) are two essential elements for plants that compete for the same uptake transporters and show conflicting interactions at the regulatory level. In order to understand the differential response to both metal deficiencies in plants, two proteomic techniques (two-dimensional gel electrophoresis and label-free shotgun) were used to study the proteome profiles of roots from tomato plants grown under Fe or Mn deficiency. A total of 119 proteins changing in relative abundance were confidently quantified and identified, including 35 and 91 in the cases of Fe deficiency and Mn deficiency, respectively, with 7 of them changing in both deficiencies. The identified proteins were categorized according to function, and GO-enrichment analysis was performed. Data showed that both deficiencies provoked a common and intense cell wall remodelling. However, the response observed for Fe and Mn deficiencies differed greatly in relation to oxidative stress, coumarin production, protein, nitrogen, and energy metabolism.
