“…Above the optimum dosage of hybrid polymer, the colour removal and COD reduction decreases. This could be due to the re-suspension of flocculated dye molecules into the supernatant [18]. The optimum pH of the hybrid polymer is similar to that of the conventional MgCl2 coagulant because the hybrid polymer consists of 90% MgCl2 and only 10% PEO.…”

Cibacron blue magnesium chloride polyethylene oxide response surface methodology (RSM) A B S T R A C TA novel inorganic-organic hybrid polymer of magnesium chloride-polyethylene oxide (MgCl2-PEO) was prepared, characterised and applied in the coagulation-flocculation of a reactive dye, Cibacron Blue F3GA (RCB). The hybrid polymers were prepared in various ratios and their conductivity and viscosities were measured. For the application in the coagulation-flocculation of RCB, the hybrid polymer of 90% MgCl2:10% PEO ratio was selected as it showed the highest conductivity and lowest viscosity. The factors that affect coagulation-flocculation of RCB, namely initial dye concentration, initial pH, agitation speed, agitation time and hybrid polymer dosage, were studied using fractional factorial design and response surface methodology (RSM). The process was also optimised, with respect to colour removal and chemical oxygen demand (COD) reduction efficiency. The five factors studied showed significant effects toward the colour removal and COD reduction of RCB. The process was optimum at initial dye concentration of 173 mg/L, pH 11.13, agitation speed of 150 rpm, agitation time of 6 minutes and hybrid polymer dosage of 1020 mg/L. Under these optimum conditions, maximum colour removal of 99.76% and COD reduction of 92.09%, were achieved.

Biomass of algae is a very potent adsorbent for absorbing liquid waste containing heavy metals and organic dyes. This study purposes to confirm the ability of adsorbents from green algae Nannochloropsis sp. modified with silica (ASN) and followed by coating magnetite particles (ASN-MPs) to absorb simultaneously the mixture of methylene blue (ME) and Cu(II) cations in aqueous solution. Simultaneous sorption of ME and Cu(II) cations to ASN and ASN-MPs was carried out by the Batch method with the interaction pH condition 7, contact time 90 minutes, and initial concentrations of ME and Cu(II) cations (0.1 - 1.0 mmol L-1). Based on adsorption data, Cu(II) cations have a greater adsorption rate and capacity (qm) compared to ME at the same contact time and initial concentration. The adsorption capacity (qm) values of the bi-component ME and Cu(II) cation mixture in ASN and ASN-MPs were 1.385 x 10-1 and 5,319 x 10-1 mmolequiv g-1, respectively, with the binary Langmuir adsorption isotherm constant for Cu(II) cations greater than ME. Modified adsorbent from algae Nannochloropsis sp. with silica matrix and magnetite particle coating, is an adsorbent that has a high effectiveness in the collective sorption of ME and Cu(II) cations. Therefore, these adsorbents can be used for the adsorption of cation mixtures of heavy metals and organic dyes that are cationic in solution.

“…To increase the capacity and rate of algal adsorption on adsorbents as well as physical and chemical stability, various attempts were made including modifying algal biomass using various supporting matrix in the form of inorganic and organic materials [2,15]. Materials produced from inorganic-organic hybrids, such as algal-silica hybrids, are promising substances for poisonous dye and heavy metal ion adsorbents [17,18].…”
