“…Sisa pewarnaan tersebut menjadi limbah cairan yang berwarna. Beberapa metode pengolahan limbah cair yang dapat dilakukan diantaranya metode elektrokoagulasi (Merzouk et al, 2009), dengan mikroba (Jing et al, 2014), dan adsorpsi (Gomes, Piccin, & Gutterres, 2016;Lin, Gung, Wu, & Suen, 2015).

Methylene blue was one of the dyes which used in industry. It is an organic compound that dangerous and could disturb biota aquatic if it throws away in the river without preparation. Hence, it needs a treatment in liquid dye waste that could reduce degree of dye. The aim was to analyse reaction kinetic of methylene blue adsorption by egg shell. One of the treatments was adsorption. Synthesized egg shell were analysed by using FTIR to know some function groups. The reaction kinetic experiment was done to count in adsorption dye process, especially in the wastewater from textile industry. Dyes adsorption by using egg shell has equilibrium time at the 70 minutes after adsorption process. Then, the process has not a different significantly. The experiment data were fitted into the Langmuir and Freundlich isotherm. Based on adsorption data, the R 2 value of Langmuir isotherm model was the highest, 0.9986 with adsorption capacity (As) 0.3589 and adsorption coefficient (Kb) 0.7962. The adsorption kinetics of methylene blue on egg shell could be described by a pseudo second order model, with the regresion, R 2 0.9979. Keywords: kinetics, adsorption. egg shell, methylene blueMetilen biru merupakan salah satu zat warna yang digunakan dalam industri. Senyawa ini merupakan senyawa organik yang berbahaya dan mengganggu ekosistem akuatik jika dibuang ke perairan. Oleh karena itu, perlu perlakuan khusus untuk mengurangi kepekatan warnanya, diantaranya melalui proses adsorpsi. Tujuan penelitian ini adalah untuk menganalisis kinetika reaksi adsorpsi metilen biru pada cangkang telur. Sintesis cangkang telur dianalisis menggunakan FTIR untuk mengetahui gugus fungsi di dalamnya. Uji kinetika reaksi dilakukan untuk dijadikan sebagai tolok ukur dalam penyerapan zat warna. Adsorben zat warna oleh cangkang telur memiliki waktu kesetimbangan pada menit >70. Evaluasi data eksperimen adsorpsi dilakukan pada model isoterm Langmuir dan Freundlich. Data adsorpsi yang sesuai adalah model isoterm Langmuir dengan nilai regresi tertinggi sebesar 0,9986; kapasitas adsorpsi (As) sebesar 0,3589 dan koefisien adsorpsi (Kb) sebesar 0,7962. Model kinetika reaksi adsorpsi metilen biru menggunakan cangkang telur cenderung pada pseudo orde 2, dengan nilai R 2 0,9979.

“…Thus, such solution cannot be used to correct the optimum area of the process in operation mode under changing production conditions. Plackett-Burman plan in the paper [6] is used to decrease the number of factors from 7 to 4. The survey of the full factorial experiment to study the process of chrome tanning with the use of modern polymer material -a derivative of maleic acid is shown in [7].…”

“…The rational conditions of tanning are identified. It should be noted that the Harrington's desirability function used for the formation of the generalized criterion of optimization is performed in the papers [6,7]. With this approach, the formation of optimization criterion depends on the experience of the researcher [8].…”

“…The approach proposed in [5][6][7][8] to solve the optimization problem is associated with the complexity of the formalization and requires a significant amount of calculations. In papers [10,11] it is shown that in some cases the wrong selection of driving directions to the optimum does not lead to the desired result.…”
