This research had an aim to develop an autoclave for using in natural dyes extraction and dyeing process. The autoclave used the stainless steel as the major material what it was a noble durable material and good resistance for the chemical used in the processes. The achievement results showed by the comparison data between the conventional process and the development using autoclave in term of extraction efficiency deep of shade (K/S) time equivalent process time and amount of gas consumption saver. The knowledge from the research would transfer to the target group at Bann Yang Nam Klad Tai Phetchaburi province. The results were following as 1. For the extraction process: the extraction process using 100oC for 45 min. They obtained product was the same dye quality but the autoclave process was smaller water evaporation as 26.71% whereas the conventional process was 41.99%. 2. For the dyeing process: All condition from the autoclave using make a deeper dye shade (K/S) than conventional process. The dyeing time equivalent as 15 minutes to make the depth shape via autoclave process as alike the conventional process for 45 min. 3. Saving time and gas consumption: the autoclave process could save 66.67% time process and 88.99% amount of gas consumption. 4. The Complacency for knowledge assignment: the satisfaction level in the content time and period was good. Furthermore the utilization the instructors and the value obtained were excellent. This research accomplished the study objectives. The results were not only corresponding to energy conservation but them also reducing the chemical toxic and pollutant vapor inhalant to the worker.

In this study autoclaved aerated concrete (ACC) were investigated as low-cost andsimple adsorbents for removal of Pb(II) from aqueous solution. The adsorption of Pb(II) wascarried out by batch experiments as a function of solution pH adsorbent dosage contacttime initial Pb(II) concentration and temperature. The experimental data were analyzed bythe Langmuir Freundlich Temkin and D-R isotherm models. The Langmuir isotherm modelis more suitable. The monolayer adsorption capacity of ACC was found to be 3.99 mg g−1.The adsorption of Pb(II) onto ACC was physical in nature. The kinetic studies of Pb(II)demonstrated that the adsorption of Pb(II) onto ACC adsorbents followed a pseudosecond-order model with a good correlation.
