Modeling, simulation and estimation of parameter in batch adsorption system of dye removal / Kan Chee Kit
Pemodelan dan simulasi penjerapan kelompok dalam penyingkiran pencelup yang menggunakan karbon teraktif daripada sisa kulit kacang tanah telah dikaji. Model matematik telah diterbit berdasarkan model dwi-rintangan yang termasuk koefisien pemindahan jisim luaran dan koefisien resapan liang yang mengawal proses pemindahan jisim dalam penjerapan kelompok. Program MATLAB telah ditulis untuk menyelesaikan persamaan kebezaan biasa daripada model tersebut dan menganggar parameter pemindahan jisim dengan memadankan data simulasi dengan data eksperimen daripada tulisan. Koefisien pemindahan jisim luaran kf dan koefisien resapan liang Dp masing-masing telah dianggar sebagai 6.2054×10-2 m/s dan 2.2660×10-10 m2/s. Dengan menggunakan parameter yang dianggar, keputusan simulasi menunjukkan model tersebut boleh memberi korelasi yang baik dengan data eksperimen berdasarkan kepekatan permulaan yang berlainan. Parameter yang dianggar telah digunakan untuk mengaji penjerapan di bawah faktor-faktor yang berlainan seperti kepekatan pecelup permulaan, isipadu larutan pencelup, saiz partikel penjerap dan jisim penjerap. Kesimpulan dibuat bahawa kecekapan penyingkiran pencelup adalah lebih tinggi bagi kepekatan pencelup permulaan yang lebih rendah, jisim penjerap yang lebih tinggi, isipadu larutan pencelup yang lebih rendah dan saiz partikel penjerap yang lebih kecil. _______________________________________________________________________________________________________ Modeling and simulation of batch adsorption in dye removal using activated carbon prepared from groundnut shell waste was studied. Mathematical model was developed based on a two-resistance model which included external mass transfer coefficient and pore diffusion coefficient that controls the mass transfer process in batch adsorption. MATLAB program was written to solve ordinary differential equation from the model and to estimate mass transfer parameters by matching the simulation data with the experimental data from literature. External mass transfer coefficient kf and pore diffusion coefficient Dp were estimated to be 6.2054×10-2 m/s and 2.2660×10-10 m2/s respectively. Using the estimated parameters, simulation results showed that the model provided good correlation with the experimental data based on different initial concentrations. The estimated parameters were used to study the adsorption of dye under different factors such as initial dye concentration, volume of dye solution, adsorbent particle size and mass of adsorbent. It was concluded that the dye removal efficiency was higher for lower initial dye concentration, higher mass of adsorbent, lower volume of dye solution and smaller adsorbent particle size.
