The purpose of this research is to study the heavy metal removal from wastewater from laboratory by using adsorption process with firebricks. Waste water was collected among three courses of laboratory such as analytical chemistry principle chemistry and chemistry for engineers. The optimized absorption efficiencies of multi-elements with stirring time volume ratio and temperature were 2 hours 10 g/100 mL and room temperature respectively. It was found that absorption efficiencies of lead (Pb) copper (Cu) zinc (Zn) chromium (Cr) were 65.1 54.8 63.4% and ND respectively.

The purpose of this research were to study the needs in the instruction development ot the Faculty of Science and Technology in Raiamangala University of Technology PhraNakhon according to the students and the teachers perception. The study target groups consist of 220 students and 45 teachers. The tool used was the questionnaires. The data anaalysis was the percentagethe mean and the standard deviation. It was found that the needs in the instruction development according to the students perception was the building area at the hign level. and the minimum need was the assessment and evaluation of the instruction.The needs in the teachers perception is the budget management As for the teachers needs it was shown that the administrators should buy sufficient instructional materials and they should find external budget to develop the faculty in various topics effciently. As for general administration their needs were that the administrators should develop the faculty information system to be always up-to-date.

The purpose of this study was to investigate the effectiveness of cooperative education science and technology to the development potential of the second degree. Barriers to education in response to student performance in the workplace. To study the factors and elements that allow the establishment of a cooperative education student performance increased in the first semester of the 2554 academic year.

The objectives of this research were to study present problem and barrier factors and the development of science and technology research co-operation model for Thai Public Higher Education Institutions. The samples were 388 executives in 8 Thai Public Higher Education Institutions. The instruments were questionnaire survey executive interviews and query data. Data analysis were statistical and content analysis. It was found that Thai Public Higher Education Institution policy supported the research. These were co-researches co-devices and exchanged expert researcher in knowledge. The successful factors were capitals benefits shared goals quality development and increased researches based research system the expert persons research resources reward and motivation and draft model with 4 elements: structured cooperation research funding support standard and mechanical cooperation and types of unit administration. When the draft model was completed it was brought to Connoisseurship meeting for science and technology research co-operation model for Thai Public Higher Education Institutions.

The objectives of this research were to 1) study perceived problems of students for educational management of Science and Technology Faculty Rajamangala University of Technology Phra Nakhon 2) compare perceived problems of students for educational management classified by gender students year and field of study and 3) study needs of students for educational management of Science and Technology Faculty. The sample studied were 140 undergraduate students selected by proportional stratified random sampling categorized by students year of study and simple random sampling was also used. The data was collected through questionnaires constructed by researcher. The statistics used for data analysis were mean standard deviation one way analysis of variance and Scheffes multiple comparison method.
